Homework Statement
A 20 kg block is on a surface where the coefficient of friction is 0.30. Find the minimal force needed to have the block more slowly at a constant speed.
The Attempt at a Solution
So I did coefficient of friction(mass)(gravity)=frictional force
20(0.3)(9.8)=58.86 N is the frictional force
Now is the minimal force needed to move the block like 58.87?
