A 120kg fridge requires 610N to just move it across the floor, if the coefficient of kinetic friction is 0.2, determine the force required to continue pushing it s constant velocity.
Answered by Nonetheless
Constant velocity means net force is 0.
Fa + Fk = 0
Fa + (120 kg)(-9.81 m/s^2)(0.2) = 0
Fa = 235.44 N
