A diver runs horizontally off the end of a diving board with an initial speed of 1.75 sec. If the diving board is 3.0 m above the water line, what is the diver’s speed just before she enters the water?

1.75 sec. should read 1.75 m/s
Equate total energy before and after dive:
=(1/2)m*1.75² + mg(3)
Cancel out m and solve for v.
g=acceleration due to gravity = 9.81 m/s².
