Question

Calculate the work done in pushing a box through a distance of 50 m against the force of friction equal to 250 N. Also state the type of work done.​

Answer 1

Answer:

your answer is here !

Explanation:

Here, Distance moved by box = 50 m

Force acting on box = 250 N

Thus work done on box = force × displacement

= 250×50= 12500 J

Since the box moves against the force of friction, thus work done on box is negative.
