A 1200-kg car is being driven up a 5.0° hill. The frictional force is directed opposite to the motion of the car and has a magnitude of f = 524 N. A force →FF→ is applied to the car by the road and propels the car forward. In addition to these two forces, two other forces act on the car: its weight −→WW→ and the normal force →FNF→N directed perpendicular to the road surface. The length of the road up the hill is 290 m. What should be the magnitude of →FF→, so that the net work done by all the forces acting on the car is +150 kJ?

A brick of mass m = 0.48 kg is set against a spring with a spring constant of k1 = 619 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 244 N/m. The brick is not connected to the first spring and may slide freely. Now assume friction is present on the surface in between the ends of the springs at their equilibrium lengths, and the coefficient of kinetic friction is μk = 0.5. If the distance between the springs is x = 1 m, how far d2, in meters, will the second spring now compress?
