You are on in-line skates at the top of a small hill. Your potential energy is equal to 1,000 J. The last time you checked your mass was 60.0 kg. A. What is the height of the hill.

B. If you start rolling down this hill, your potential energy will be converted into kinetic energy. At the bottom of the hill, your kinetic energy will be equal to your potential energy at the top. Calculate your speed at the bottom of the hill.
