Question

a horizontal force of 5 N is required to maintain a velocity of 2 m/s for a block of 10 kg mass sliding over a rough surface. The work done by this force in one minute is

Answer 1

Answer:

600 N

Explanation:

work done = force * displacement

since the block goes in uniform velocity the displacement will be

= speed * time   =  120 m

now fore  =  5 N

there fore work done =  600 N
