Question 174

A child climbs to the top of a playground slide and gains 1200 J of gravitational potential energy.

She then slides down to the bottom. At the bottom of the slide, her kinetic energy is 350 J.

How much energy was transferred to the surroundings as thermal energy and sound energy as she moved down the slide?

A

350 J350\text{ J}350 J

B
