1. A 75 kg. man steps off the end of a diving board, and hits the water at 7.7 m/s. Ignoring air resistance, what was the mans PE (potential energy) right before he stepped off the diving board?
I got 2223.375 Joules after Damon helped me...am I right?
2. How high is the diving board?
I got 29.645 meters after Damon helped me.
Did I make any mistakes???
