A 17 kg child descends a slide 3.5 m high and reaches the bottom with a speed of 6.0 m/s. How much work was done by friction as the child goes down the slide?

Subtract the kinetic energy gain from the potential energy loss. The remainder is friction work

a 100kg person slides down a 50m slide and reaches the bottom with a speed of 22m/s. how much thermal energy due to friction was generated in the process?
