Question 30

A child slides down a water slide.

a.

As the child slides down, the decrease in their gravitational potential energy is 1.715 kJ. The mass of the child is 50 kg. The gravitational field strength is 9.8 N/kg. Calculate the change in vertical height of the child.

[3]
b.

As the child moves down the slide, their increase in kinetic energy is less than their decrease in gravitational potential energy. Explain why.

[2]
c.

Different children have different speeds at the bottom of the slide. Explain why.
