Question

A body of mass 37 kg rests on a rough
horizontal surface. The minimum
horizontal force required to just start the
motion is 68.5 N. In order to keep the
body moving with constant velocity, a
force of 43 N is needed. What is the value
of a) coefficient of static friction? and b)
coefficient of kinetic friction?​

Answer 1

Answer:

1. 0.188

2. 0.118

Explanation:

Since it just takes the above mentioned forces to move the block, so we equate it with the frictional forces, both in static and in motion. The calculations are provided.
