you push a 25 kg box across a wooden floor at constant speed. how much force do you exert on the floor? (mu(k) = 0.20
The Attempt at a Solution
this is wat i get so far
mass = 25kg
is this correct? im confuse coz...
if the coefficient of friction between a 30 kg metal block and the floor is 0.16, what force is required to roll this block across the floor at a uniform speed? how much work is done? find : weight of force, normal force, force applied and fricitional force
