A daring ranch hand sitting on a tree limb wishes to drop vertically onto a horse galloping under the tree. The constant speed of the horse is 10.0 m/s, and the distance from the limb to the level of the saddle is 3.00 m. (a) What must be the horizontal distance between the saddle and limb when the ranch hand makes his move? (b) For what time interval is he in the air?
A glider on an air track carries a flag of length through a stationary photogate, which measures the time interval td during which the flag blocks a beam of infrared light passing across the photogate. The ratio vd = /td is the average velocity of the glider over this part of its motion. Suppose the glider moves with constant acceleration, (a) Is vd necessarily equal to the instantaneous velocity of the glider when it is halfway through the photogate in space? Explain. (b) Is vd equal to the instantaneous velocity of the glider when it is halfway through the photogate in time? Explain.

21. You are flying a small aircraft to deploy an instrument in the ocean. You decrease your altitude to 120ft and fly horizontally at 73mph straight east. When you are ready to deploy, you log your GPS position, and drop the instrument. *The acceleration due to gravity near the surface of the earth is -32ft/s^2. Use 1mi=5280ft and 1hr=3600s How long does it take the instrument to hit the water? b. How far has it traveled from the GPS position you logged? Give you answer in ft. What is the magnitude of the velocity the instant before the instrument hits the water? d. We know we are neglecting drag when we are calculating trajectories with the kinematic equations. It can be shown that the kinematic equations are sufficiently accurate as long as the object is small and compact (we'll assume our instrument is) and travels less than 98mph. Based on this knowledge, do you think our approximation of this problem is accurate or not? Explain. а. с.

3.) You throw a ball straight up. The ball leaves your hand at a height of 2.00 m above the ground with a speed of 20.0 m/s (~45 mph). Ignore air resistance and use g = 10.0 m/s2 to answer the following questions. You can use a spreadsheet but show your sample calculations. 3a.) Calculate the height, y(t), and velocity, vy(t), at 0.50 second intervals until the ball hits the ground. Show your results in a table and put the units in the column headers: t (s), vy (m/s), y (m). 3b.) Use this data to draw a motion diagram for the ball at 0.50 second intervals. Label the height and the speed at each time interval. Label the origin, starting height, maximum height, and final height. Include the velocity vectors for each time and location of the ball. 3c.) Calculate the time it takes for the ball to hit the ground and the final velocity of the ball just as it hits the ground. Include this velocity vector in your diagram.
