Question

Moe is carrying and supporting a large crate by exerting 1000 N. He is walking at constant velocity across a level, horizontal floor. If he covers a distance of 10 meters, how much work does he do on the crate? Use g = 10m/s2 if needed. Ignore friction between Moe and the crate.

Answer 1

To solve this problem it is necessary to apply the agreements related to Strength and Work.

Work is defined as the amount of energy required to move a force over a certain distance.

$W = F*d$

Where,

F = Force

d = distance

Our values are given as,

F = 1000N

d = 10m

Therefore replacing,

W = 1000*10

W = 10000J

Therefore the neccesary work is 10000J or 10kJ.
