1If a ball is thrown vertically upward with an initial velocity of 15 m/s, what is its acceleration at the very top of its path, assuming no air resistance?
2An object is released from rest on a distant planet and falls 5.23 meters during the first second. What is the magnitude of the acceleration due to gravity on this planet?
3According to the principles of free fall, which of the following statements are true about an object dropped near the Earth's surface (neglecting air resistance)?
4A ball is thrown straight up with an initial speed of 8.9 m/s. Calculate the maximum height it reaches. Use g = 9.8 m/s^2.
5A boy stands on a 1000 m cliff and throws a ball downward at 20 m/s. Using g = 10 m/s^2, how high above the ground is the ball after 6 seconds?
6If you throw an object downward instead of dropping it, how does its acceleration during the flight compare to its acceleration if it were dropped?
7A tennis ball is thrown vertically upward with an initial velocity of +7.1 m/s. What will its velocity be when it returns to its starting point, assuming no air resistance?
8A ball is thrown upward with a speed of 10 m/s. How long does it take to reach its highest point? (Use g = 10 m/s^2)
9Which characteristics describe the velocity-time graph of an object thrown vertically upward and then caught at the same height?
10An apple falls from a tree and hits the ground 12 m below. With what speed will it hit the ground? (g = 9.8 m/s^2)
