Compare and contrast contact forces and action-at-a-distance forces. Give an example of each type of force. A case is experiencing a 165 N frictional force sliding across ice, what is the normal force the ice exerts on the steel? The coefficient of friction is k = 0.44. Show all work to get full credit. Describe the inertia of your body as you approach the bottom of a hill in your car and begin to go up the other side. Be sure to include the direction the car is traveling, the direction you are traveling, and the sensation your body will feel. A man is pushing a 240 N lawn mower across the lawn. The handle of the lawn mower is at an angle of 35 degrees. The man must overcome a friction force of 120 N to keep the lawn mower moving at a constant velocity. Calculate the normal force that the ground is providing to the lawn mower. Show your work and refer to the image provided to analyze the forces.
