At a playground, a 19-kg child plays on a slide that descends a total of 2.3 meters (vertically). The child starts out at rest at the top of the slide. During the child’s descent, friction does -361 J of work on the child. What speed does the child have at the bottom of the slide?

A 15.0 kg child descends a slide 2.8m high and reaches the bottom with a speed of 2.3 m/s. How much thermal energy due to friction is generated in this process?
A 33 kg child slides down a playground slide at a constant speed. The slide has a height of 4.0 m and is 8.0 m long.
A 33 kg child slides down a playground slide at a constant speed. The slide has a height of 4.0 m and is 8.0 m long. Part A Using the law of conservation of energy, find the magnitude of the kinetic friction force acting on the child.

A 18.0 kg child descends a slide 2.30 m high and reaches the bottom with a speed of 1.90 m/s . How much thermal energy due to friction was generated in this process?
A 18 kg child slides down a 4.0 m-high playground slide
A 18 kg child slides down a 4.0 m-high playground slide. She starts from rest, and her speed at the bottom is 2.8 m/s. What is the change in the thermal energy of the slide and the seat of her pants?
