Explanation:
We first assume that no energy is lost while sliding down (i.e. no friction).
The gravitational potential energy at the top of the slide is given by
At the bottom of the slide, his gravitational potential energy is
Since we assumed that no energy is lost, the sum of the energy on top of the slide is equal to the sum of the energy at the bottom of the slide. Therefore,
