A24 kg child slides down a 3.3-m-high playground slide. she starts from rest, and her speed at the bottom is 3.0 m/s. a. what energy transfers and transformation occurs during the slide? b. what is the total change in the thermal energy of the slide and the seat of her pants?

(a) Potential energy of the child is converted into the kinetic energy at the bottom off the slide and a part of which is lost into friction generating heat between the contact surfaces.

(b)

Explanation:

Given:

(a)

∴The initial potential energy of the child is converted into the kinetic energy at the bottom off the slide and a part of which is lost into friction generating heat between the contact surfaces.

Initial potential energy:

Kinetic energy at the bottom of the slide:

(b)

Now, the difference in the potential and kinetic energy is the total change in the thermal energy of the slide and the seat of her pants.

This can be given as:

a and c

explanation:

both a and c are correct answers to my knowledge, it's been a bit since i've done anything related to magnetic fields, but it should be right.
