Which produces the greater change in kinetic energy (assume that all of the work goes into kinetic energy)?
A)exerting a 10 N horizontal force through a distance of 5 m
B)exerting a horizontal force of 20 N through a distance of 2 m
C)exerting a 30 N horizontal force through a distance of 1.5 m
D)exerting a horizontal force of 40 N through a distance of 1m

Quizplus · Accepted Answer

The work done, which equals the change in kinetic energy, is calculated as force times distance. For option A, the work done is 10 N * 5 m = 50 J, which is greater than the work done in the other options.
