Shown in the figure below is a magazine resting on top of a book. There is static friction between the magazine and the book and there is kinetic friction between the book and the table. If you pull very gently on the book, both objects slide together. If you pull very forcefully, you will slide the book out from under the magazine. In this problem, we will determine the MAXIMUM FORCE that you can apply and still have the magazine come along for the ride.

The vehicle shown starts from rest at the bottom of the hill and accelerates up the hill due to the force FR from the road. Note that this is a static friction force and is not dissipative. Vrop = 9.7 m/s m = 1600 kg h = 50 m FR = 7300 N 0 = 25° A) If the vehicle reaches the top of the hill with the speed shown, how much thermal energy is dissipated in the process? B) Assuming that air drag, Fang , is the only dissipative force during this process, try to estimate the cross-sectional area of the vehicle "seen" by the air. In the formula for air drag, regard the car's speed as being a constant v = 5.0 m/s (this speed is roughly half of the starting and ending speeds). Use C = 0.5 for the drag coefficient and p = 1.25 kg/m³ for air density.
