More motion problems - sorry for delay

1. A car, starting from rest, gets up to a speed of 30 m/s in 8 seconds. Find:

A. The cars acceleration
B. The distance traveled by the car in this time

2. You drop a ball from a height of 28 m. Find the time for it to hit the ground and the speed it has immediately before impact.

3. If you were to throw a ball straight up at 15 m/s, how long would it take to reach apogee? How high would it travel?
