A car accelerates from rest to a velocity of 5 meters/second in 4 seconds. What is its average acceleration over this period of time?

A baseball player is dashing toward home plate with a speed of 3.8 m/s when she decides to hit the dirt. She slides for 1.3 s, just reaching the plate as she stops (safe, of course).

The water that powers the generators enters and leaves the system at a low speed (thus we can neglect its change of kinetic energy) and loses 160 m of altitude during the process.
