1. Consider a ball dropped from rest. Find the following:
a. How fast it is traveling after 2.5 seconds of freefall
b. How far it will have fallen in this time
2. You throw a ball straight up into the air with an initial speed of 35 m/s.
a. How long will it take to reach apogee (highest point)?
b. How high will it rise?
c. How long will it take (total) to return to your hand?
d. What will be the velocity immediately before returning to your hand?
3. An object falls to the surface of a new planet from rest, starting at 10 m above the ground. It takes 2 seconds to hit the ground. What is g on this planet?
4. How does the time to fall from a certain height on the Moon compare to the time to fall from the same height on Earth? (g on the Moon is 1/6 that of Earth) Determine a general relationship, if you can. If not, pick a specific height.
