On planet #5, a stone dropped from a height of 64.3 m above the ground will hit the ground at a speed of 60.9 m/s. What is the value of g for planet #5?   A 28.84 m/s^2   B 33.94 m/s^2   C 57.68 m/s^2   D 67.89 m/s^2

You go watch your friend as she runs at a cross country meet. The first time she passes you, your friend runs by going due north at a speed of 4.40 m/s. You move to a different place on the course and twelve minutes after you saw her the first time, your friend runs past you again. This time she is traveling at a speed of 3.80 m/s in the direction 30.0◦ W of S. What is the direction of her average acceleration between those same two times?

You shoot a ball straight up with an initial speed of 8490 m/s. When the surface of the earth, what is the speed of the ball? O 2146 m/s reaches a height of 4.0 x 10 6 m above O 2956 m/s O 3546 m/s 4009 m/s 4588 m/s O 4876 m/s

On planet #3, you fire a projectile horizontally from the edge of a vertical cliff 76.0 m above the ground, with an initial speed of 31.2 m/s. The projectile lands 71.5 m away from the base of the cliff. What is the value of g for planet #3?     848.50 m/s^2     28.94 m/s^2     14.47 m/s^2     12.05 m/s^2

Tarzan grabs a vine hanging vertically from a tall tree when he is running at 9.3 m/s. a. How high (in m) can he swing upward? (Enter your answer with respect to the ground.) (Answer in m) b. Does the length of the vine affect this height? (Yes or No)

You want to visit your friend in Seattle and decide to take the train. Unfortunately, you are late getting to the train station. You are running as fast as you can, but 30 meters ahead of you the train begins to pull out. You can run at a maximum speed of 8 m/s and the train is accelerating at 1 m/s². In 50 meters you will reach a barrier. Can you catch up to the departing train? Argue why you should or should not jump onto the moving train?
