Asked by Meder
A child with a mass of 35.0 kg climbs onto a water slide that is 2.00 m
above the water as shown. The child does not push off, and so is at rest
when the sliding begins. The slide is very slippery, and is considered frictionless.
(i) What is the work done by the normal force on the child?
(ii) What is the work done by the gravitational force over the slide?
(iii) What is the speed of the child when he/she enters the water?

1. Work = mg*h
Work = 343 * 2 = 686 J.
3. V^2 = Vo^2 + 2g*h
V^2 = 0 + 19.6*2 = 39.2
V = 6.26 m/s.
