Can someone please help me solve this question below.
1. Homework Statement
How much force is needed to push a 20 kg box across a floor at a constant speed of 0.5 m/s [forward] against a frictional resistance of 4 N?
Fnet = m.a
Since the velocity is constant, the acceleration will be 0. If that is correct the net force is going to be 0, which doesn't make any sense.
