Kartianna is pushing a lawn mower using a force of 300 N. If she pushes the mower a distance of 800 m, how much work has she done?

a
240,000 J

b
1,100 J
c
24,000 J
d
24,000 J

The work done is equal to the force applied times the distance moved in the direction of the force. Therefore, the work done by Kartianna is equal to the force of 300 N multiplied by the distance of 800 m.

Work = Force x Distance
Work = 300 N x 800 m
Work = 240,000 J

Therefore, Kartianna has done 240,000 J of work.

The correct answer is a) 240,000 J.
