Question

C. i) A block of mass of 2 kg with constant velocity is pushed along a table by a

force of 5N, what is the magnitude of the force opposing its motion?

Answer 1

The Force of Friction:

Friction is a self-adjusting force. The block in the question is moving with constant velocity under the force of 5 N. This implies that the force of kinetic friction acting on the block is also 5 N, acting opposite to the applied force and net force on the block is
