A 20 Kg block is initially at rest. A 70 N force is required to set the block in motion. after the motion 60N is applied to keep block moving with constant speed.the coefficient of statistic friction.

Writing the balanced equation fo the block as:
f = uN = 70 (least condition)
200*u = 70
u = 70/200=> 7/20
