A baby pushes a toy ball in a straight
line using 12.6 N of force, and the toy
ball has a final kinetic energy of 32.9 J.
What distance did the toy ball roll?
d = [?] m

Answer:

2.61 m

Explanation:

The work-energy theorem says that the work done on an object is equal to its change in kinetic energy. Work is equal to force times distance, and kinetic energy is half the mass times the square of the speed.

W = ΔKE

Fd = KE

(12.6 N) d = 32.9 J

d = 2.61 m
