Question

A box of mass 2 kg is being pushed horizontally by 10 N
force for 60 cm along the floor. During the first 20 cm,
the friction between the box and the floor is 4 N, and the
friction for the rest of the distance is negligible. What is the
work done on the box by the 10 N force?​

Answer 1

Explanation:

As was mentioned, work = force x distance. With friction, force = uN where N is the force between two surfaces, and u is the co-efficient of sliding friction ( static friction does no work whatsoever, since there is no distance involved ).

Answer 2

Answer:

Answer for this question is 6J

Explanation:

Not Satisfied with the answer buy i know the ans and how to solve it

Solve it by first finding kinetic energy and then work done = W= fd
