A 20 kg child slides down a 3.0-m-high playground slide. She starts from rest, and her speed at the bottom is 2.0 m/s. a. What energy transfers and transformations occur during the slide? b. What is the total change in the thermal energy of the slide and the seat of her pants? A hockey puck is given an initial speed of 5.0 m/s. If the

A 25 kg child slides down a 4.0 m high playground slide. She starts from rest, and her speed at the bottom is 1.0 m/s. What is the thermal energy that was released in this process? Hint: Consider the initial and final energies.

A child whose weight is 267 N slides down a 6.1 m play-ground slide that makes an angle of $20^{\circ}$ with the horizontal. The coefficient of kinetic friction between slide and child is 0.10 (a) How much energy is transferred to thermal energy? (b) If she starts at the top with a speed of 0.457 $\mathrm{m} / \mathrm{s},$ what is her speed at the bottom?
