Compute all parts of given question:
Question: A person pushes a 16.0kg lawn mower at constant speed with a force of 89.0N directed along the handle, which is at an angle of 45.0 degrees to the horizontal.
Part A: Draw the free-body diagram showing all forces acting on the mower.
Part B: Calculate the horizontal friction force on the mower.
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 1.6m/s in 2.5 seconds, assuming the same friction force?
I need help to find the horizontal friction force on the mower.
