A person pushes a 12.5 kg lawn mower at constant speed with a force of 89.0 N directed along the handle, which is at an angle of 45.0° to the horizontal.
Part A:
Draw the free-body diagram showing all forces acting on the mower.
Draw the vectors starting at the black dot. The location and orientation of the vectors will be graded.
Part B:
Calculate the horizontal friction force on the mower.
Express your answer to three significant figures and include the appropriate units.
Part C:
Calculate the normal force exerted vertically upward on the mower by the ground.
Part D:
What force must the person exert on the lawn mower to accelerate it from rest to 1.6 m/s in 2.5 seconds, assuming the same friction force?
