A 58 kg skier starts at rest from a 24.0 m high hill. They travel to the bottom and then up a second hill to a height of 19.0 m. How much kinetic energy do they have at the top of the second hill?

10.791 kJ

Explanation:

Given that,

Mass of the skier, m = 58 kg

Initial position, h₁ = 24 m

Final position, h₂ = 19 m

We need to find the kinetic energy do they have at the top of the second hill.

Using the conservation of energy for both positions.

And

Kinetic energy :

So, the kinetic energy they have at the top of the second hill is 10.791 kJ.
