4 Part A Jill claims that her new rocket is 104 m long. As she flies past your house, you measure the rocket's length and find that it is only 72 m. What is Jill's speed, as a fraction of c? ΜΕ ΑΣΦ 20 ? v =

In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .

I was able to understand the attached problem and have the answer now for mu.  So the equation I have is  v=150e-6.0788 x My question, then, is how do we find the TIME to slow the sled to 15 mi/hr ? The answer is supposed to be 35.533 seconds, but I don't know how to get that.  Thanks!

Light speed c = 3.0* 108 m/s. A light year is a distance light travels in one year. Calculate a light-year in [a] km and [b] Mile

In this problem, I am suppose to manipulate the equation to find what r equals to. Thank you.

A student wakes up late and runs to school, covering a distance of 2.55 km in the direction of [N20degrees E] as measured from her home. She then realizes that her friend Lydia has her homework and races over to his house 0.5 km away [W] from the school. The two friends then decide it’s not worth going to class late so they go off to the mall that is 2.8 km [W50degreesS]. a)  What is the students total displacement? b)  If the total time taken by the student to run to school then over to the friend’s house was 25 minutes, what was her average velocity?

According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?

Alishba wakes up late and runs to school, covering a distance of 2.55 km in a direction of [N200 E] as measured from her home. She then realizes that her friend Lydia has her homework and races over to his house 0.5 km away [W] from the school. The two friends then decide it’s not worth going to class late so they go off to the mall that is 2.8 km [W500 S].  a) What is Alishba’s total displacement? b) If the total time taken by Alishba to run to school then over to the friend’s house was 25 minutes, what was her average velocity?
