A man pushes a 2.0 kg broom at CONSTANT SPEED across the floor. The broom handle makes a 50° angle with the floor. He pushes the broom with a 5.0 N force.

a) Sum the forces in the y-direction. What is the value of the normal force?
b) Sum the forces in the x-direction. What is the value of the frictional force opposing the motion?
c) If the frictional force were suddenly reduced to zero, what would happen to the broom (ANSWER: The broom would probably have Fnet)?

I will work out the problems but please tell me if I'm right!
