Problem 1 - Friction A person is pushing a supermarket cart by applying a force F = 15 N at an angle 0 = 30° below the horizontal direction. Assume that there is kinetic friction between the cart and the floor. The coefficient of kinetic friction is 4k = 0.851. The mass of the cart is m = 12.5 kg. a) Draw the free body diagram for the cart. b) Find the magnitude of the kinetic friction force applied to the cart. b) Find the acceleration of the cart.
