4. A person pushes a 14.0 kg lawn mower at a constant speed with a force F= 88.0 N directed along the handle which is at an angle of 45.0 to the horizontal as shown in the diagram below. hahaha Was.o Draw a Free Body Diagram A) Draw a free body diagram showing all forces acting on the lawn mower. B) Calculate the horizontal force of friction on the mower C) Calculate the Normal force exerted vertically upward on the mower by the ground D) What force must be exerted by the person on the lawn mower to accelerate it from rest to 1.5 m/s in 2.5 seconds assuming the force of friction remains the same
