Question

As you slide a heavy box across the floor, friction applies a force of -1 00 N

over a distance of 5 m, How much work is done by friction?

Answer 1

-500 J

Step-by-step explanation:

Answer 2

W = 500 N

Step-by-step 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.
