Question

At a playground, a 22kg child plays on a slide that drops through a height of 2.1m. The child starts at rest at the top of the slide. On the way down, the slide does a nonconservative work of -371J on the child.

What is the child's speed at the bottom of the slide?

Answer 1

V^2 = Vo^2 + 2g*h.
Vo = 0.
g = 9.8 m/s^2.
h = 2.1 m.
V = ?

Answer 2

idk lol
