Velocity and Acceleration (Tatiana Stantcheva) Purpose of this lab To analyze the motion of the NASA/SpaceX Falcon 9 rocket during its first 3 minutes. Here is a recording of the launch that occurred at 3:22 pm on May 30, 2020 https://www.youtube.com/watch?v=TxBj8R7XKe4 https://youtu.be/MokKBDaSjUA Alternative video to adjust Activity 1. Collecting Data from the Video Open a spreadsheet and record the velocity of the Falcon 9/Crew Dragon for the first 3 minutes in increments of 5 seconds, beginning from T0 to T+00:03:00 The velocity in km/h is given in the lower-left corner of the video. Use the launch counter for the time, e.g. T+00:00:15 is time marker of 15 seconds after launch. Here is an example of how your spreadsheet should look like. You should have about 25 entries - data for the first 3 minutes of the flight.
Activity 2. Data Analysis Plot of speed versus time The speed in the lower corner is given in km/h. In your spreadsheet, add a column where you convert the speed in the metric system. Here is an example of your spreadsheet: Plot the speed in m/s versus time in the second graph. (See page three.) Questions: 1. During what time intervals is the graph linear? 2:27-2:37 2. How does the graph look around the time Falcon separates from Crew Dragon? There was a slight drop in speed, and then the thruster for Falcon was initiated so the speed slightly accelerated again. y = 1.0216x

You are currently in a stable orbit 9000 km
(1km=1000m) from the center of planet Proxima
Centauri B.
According to the calculations done by NASA, Planet Proxima Centauri B has
a mass of approximately 7.6x10^24kg.
Based on fuel consumption and expected material aboard the ship, your
colony ship lander has a mass of approximately 1.1x10^5 kg.
1. Using Newton's Law of Universal Gravitation, determine what the force of
gravity on your ship at that orbit be using the early measurements
2.Using Newton's second law determine the acceleration of your lander due
to gravity
3.Upon arrival, you measure the actual force of gravity to be 6x10^5 N,which

Click to show Forces, Sum of Forces, Values, Mass, and Acceleration.
There are two experiments for this activity – make sure you include both.
Experiment #1: Acceleration vs. Force
In this lab you will determine the relationship between acceleration and net force.
Choose a mass at the beginning, and keep it constant for this entire experiment.
Set the friction to zero. This will make your Applied Force equal to the net force.
Record data for five different values of Applied Force.
Graph Acceleration vs. Net Force.
Graph this in Google sheets(you want a line graph - it should only have one line).
Make sure that Applied Force information is used as the x value
Make sure that Acceleration information is used as the y value

We want to design an experiment to measure oscillations of a simple pendulum on the surface of Jupiter with acceleration due to gravity
g= 30 ms 2. We have to make do with a rudimentary video camera with a frame rate of 15 Hz to record oscillations in a pendulum and use it
to measure the frequency of oscillation. The smallest length of the pendulum that we can send so that the correct oscillation frequency can be
measured is
cm.
Assume perfect spatial resolution of the camera and ignore other "minor" logistical difficulties with this experiment.

Interconverting pressure and force
A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 470.0 MPa. The student's
design calls for an observation port on the side of the vessel (see diagram below). The bolts that hold the cover of this port onto the vessel can safely withstand
a force of 2.80 MN.

Mountaineers often use a rope to lower themselves
down the face of a cliff (this is called rappelling). They
do this with their body nearly horizontal and their feet
pushing against the cliff (Eigure 1). Suppose that an
78.6-kg climber, who is 1.88 m tall and has a center of
gravity 1.0 m from his feet, rappels down a vertical cliff
with his body raised 40.4° above the horizontal. He
holds the rope 1.54 m from his feet, and it makes a
20.7° angle with the cliff face.
✓ Correct
Part D
Figure
1 of 1
What minimum coefficient of static friction is needed to prevent the climber's feet from slipping on
the cliff face if he has one foot at a time against the cliff?
Express your answer using two significant figures.

Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires.
Q1. I have good information that in Fast 29, Dominic Toretto (Vin Diesel) will need to refill a tire quickly during a dramatic moment. For this reason, he has a 3.00 L tank of compressed air that is under 2.7892*103 mmHg and is kept cool in dry ice at -35.0 °C.
When Dom hooks his compressed air up to his completely empty 10.50 L tire at 39.2 °C and lets it run, what will his final tire pressure be, in atm? Assume all the air is transferred into the tire. Is his tire pressure above the 2.31 atm that he needs to save the planet/his family/his crew?
Q2. Your car tire pressure sensor looks to see when your tire pressure…

In the automotive industry, supercars are highly accredited with how they are manufacture; from the
type of car chassis used to the type of materials employed. Often enough, companies like BMW,
Mercedes & Audi produces supercars that exemplifies a better reliability compared to other automotive
manufacturing companies. This is because they pay close attention to the details on how the car is
manufactured; right from raw materials to a finished supercar. The task given to you is to watch the
video link provided below & explain the electrostatic process acquired for the two different models of
BMW vehicles.

horsepower. In mathematical
terms, one horsepower is the
power needed to move 550
pounds one foot in one
second, or the power needed
to move 33,000 pounds one
foot in one minute. Power, in
physics, is defined simply as
the rate of doing work. The

- PIoVide ue comect u We want to design an experiment to measure oscillations of a simple pendulum on the surface of Jupiter with acceleration due to gravity g= 30 ms 2. We have to make do with a rudimentary video camera with a frame rate of 15 Hz to record oscillations in a pendulum and use it to measure the frequency of oscillation. The smallest length of the pendulum that we can send so that the correct oscillation frequency can be measured is cm. Assume perfect spatial resolution of the camera and ignore other "minor" logistical difficulties with this experiment.arrow_forward\ח "Chicago - Lakeshore Dr from John Hancock Center" by Ryan from Toronto, CA CC BY 2.0 This image is taken from the John Hancock Center and is an aerial view near Oak Street Beach.

Fv = 390 N Sur Previous Answers Mountaineers often use a rope to lower themselves down the face of a cliff (this is called rappelling). They do this with their body nearly horizontal and their feet pushing against the cliff (Eigure 1). Suppose that an 78.6-kg climber, who is 1.88 m tall and has a center of gravity 1.0 m from his feet, rappels down a vertical cliff with his body raised 40.4° above the horizontal. He holds the rope 1.54 m from his feet, and it makes a 20.7° angle with the cliff face. ✓ Correct Part D Figure 1 of 1 What minimum coefficient of static friction is needed to prevent the climber's feet from slipping on the cliff face if he has one foot at a time against the cliff?
