A block weighing 6.8 N requires a force of 2.9 N to push it along at constant velocity.
What is the coefficient of friction for the
Let Ff = Force of Friction
Let C = Coefficient of Friction
Let N = Normal force
Ff = CN
The required force to just get a block moving along at a constant velocity will also be equal to the force of friction (Ff) if there is nothing else acting on the horizontal plane. N can be calculated using the block's weight. So;
C = N/Ff
