Question

A box weighing 20 kg is pushed along the floor at a constant sped by applying a horizontal force .if the coefficient of friction is 0.25 then force applied is(g=10m/s^2)

Answer 1

Answer:

49N

Explanation:

Due to zero acceleration, force in positive X direction=force in negative X direction

Force by friction=0.25x20x9.8= 49N

Applied force was 49N
