QUESTION
5-kg block is moving at constant speed on a horizontal surface.
A 0.5-kg block is moving at constant speed on a horizontal surface. Thefriction force acting on the block is 20N, calculate the coefficient of kinetic friction force
Frictional force= F=Where, m= mass of block = 0.5 kg According to the question, frictional force = 20 0N So,Or,= ANS:Coefficient of kinetic friction is
