Answer:
W = 500 N
Explanation:
The force of friction acting on the box, F = -100 N
It travel a distance of 5 m
We need to find the work done by the friction. The formula for the work done is given by the product of force and distance.
W = F×d
W = -100 × 5
= -500 N
Hence, the work done is 500 N and it is in the opposite direction of motion.
