asked • 11/08/20An 2 kg wooden block slides across a horizontal wooden floor at constant velocity.What is the magnitude of the force of kinetic friction between the block and the floor?

Assuming that there are no forces propelling the block forward,
the force of friction must also be 0.
The reason is that non-0 force of friction would cause the block to decelerate.
