A man is pushing a 780 kg piano up a 7° incline. Assume up the ramp is the positive direction. a) Assuming no friction, what force must he push with to maintain a constant velocity up the ramp? Fpush = %3D b) If there were a coefficient of static friction of Hs = 0.37, how much force would he have to push with to get the piano to start moving up the ramp? Fpush N.
