Question

?

A boy moves down a waterslide from a height of 10 meters. What is his
velocity when he hits the water at the bottom of the slide? Assume zero
friction on the slide.

Answer 1

PE = W * h weight of boy ^ height

1/2 M V^2 = PE

1/2 M V^2 = M g h

V^2 = 2 g h

V^2 = 2 * 9.8 m/s^2 * 10 m

V = 14 m/s
