Question

A man does 500 J of work pushing a car a distance of 2 m. How much force does he apply? Assume there is no friction.

A. 250 N
B. 1000 N
C. 125 N
D. 500 N

Answer 1

The correct answer is A. 250N

Work is a product of force and distance.

That is, work done=force×distance

Therefore substituting for the values in the question:

500J=force×2m

force= 500Nm/2m=250N

another unit for work done is Nm as force as the SI unit of force is newtons and distance in meters

Answer 2

Answer:

250
