How much work is done by the man?

Question

A man pushes a lawn mower on a level lawn with a force of 203 N. If 49% of this force is directed downward, how much work is done by the man in pushing the mower 5.7 m?

____ J

Answer 1

Work done is F.ΔX, where F is the force in the direction of the motion.

 

F_xΔx = 203 (1-0.49)(5.7) N.m = 590.121 N
