- Consider the 65.0-kg ice skater being pushed by two others shown. Find the direction and magnitude of Ftot, the total force exerted on her by the others, given that the magnitudes F1 and F2 are 26.4 N and 18.6 N, respectively. (b) What is her initial acceleration if she is initially stationary and wearing steel-bladed skates that point in the direction of Ftot? (c) What is her acceleration assuming she is already moving in the direction of Ftot? (Remember that friction always acts in the direction opposite that of motion or attempted motion between surfaces in contact.)Consider a box of mass m that remains still on an incline. What is the free body diagram of the box.Provide a free body diagram showing object (box) skidding down the same incline (accelerating slightly down the incline). Assume the incline has a much more slippery surface, but not frictionless. Overlay a labeled force diagram on the object.

Calculate the acceleration of the car. Draw the free-body diagram with the forces, but without their magnitudes. Find the coefficient of kinetic friction, ?k , between tires and the road. (Tricky. You don’t know the car’s mass, but you don’t have to know it. The mass cancels from the equation.)
