1. The acceleration of gravity on the moon is 1.62 m/s². If a ball is dropped on the
moon from a height of 2.75 m. Determine the time for the ball to fall to the surface
of the moon.
2. A frog is capable of jumping to a height of 1.3 m. Determine the takeoff speed
of the frog.
3. A baseball is hit straight up into the air with an initial velocity of 25.2 m/s and
has a hang-time of 5.28 s. Determine the height to which the ball rises before it
reaches its peak. (Hint: time to rise to the peak is one-half the total hang-time.)
4. A stone is dropped into a deep well and is heard to hit the water 3.41 s after
being dropped. Determine the final velocity of the stone.
