Bronco Brown is mowing his lawn. He applies a force F along the handle of the lawnmower as shown. Bronco moves the mower at constant velocity.
(A.) What is the magnitude of the resistance force acting horizontally on the mower?
(B.) Why is "constant velocity" the key to solving this problem
(C.) Calculate the resistance force if Bronco applies 210N along the handle, the mower moves at 1.2 m/s, and the angle that the handle makes with the ground is 55 degrees.
