If an object force of 50 N is used to move an object a distance of 20 m, what distance must the object be moved if the input force is 10 N, so that work in = work out?

Explanation:

Given data:

Let the distance traveled by the object in the second case be

In the given problem, work done by the forces are same in both the cases.

Thus,

there are no contact forces mentioned on the list of choices that you've provided.

total distance/total time

(85 + 82)/(5+3)
