Asked by Evan
A fireman, whose weight is 500 N, slides down a pole with an constant velocity of 3 m/s. The forces that act on him are his weight pulling him down and the force of friction pulling up on him. What is the force of friction and the net force of the fire fighter?

he has a constant velocity (zero acceleration)
so the net force on him is zero
the frictional force must equal his weight
so the net force on him is zero
the frictional force must equal his weight
