1. A ball is dropped from rest from 28 m above the ground. Find the time to fall and speed (before impact with ground).
2. A runner accelerates for 10 seconds, then maintains that speed for 15 seconds, then slows to a stop in 5 seconds. After this, they stand still for 20 seconds before accelerating for 5 seconds to get to a new speed.
Draw graphs of d vs. t, v vs. t, and a vs. t for this runner.
3. A physics book is kicked horizontally off of a cliff at 10 m/s. The cliff is 20 m high. How long will it take to hit the ground, and how far from the base of the cliff does it land?
4. Create a conversion factor to convert ft/sec to miles/millennium.
