A car of mass 1110 kg enters a banked turn with a banking angle of 11.1° and a radius of 300 m at a speed of 30.0 m/s. The coefficient of static friction between the car’s wheels and the pavement is 0.0881. The turn covers a total of 1 45°.
(a) If the car experiences a drag force that of D=kv where k=32.0kg/s, how much thrust must the car provide to maintain constant velocity in the turn?
(b) If the engine of the car suddenly cuts out at 2.10 s after entering the curve, and the only tangential force acting on the car is the drag force, how fast will the car be traveling by the time it exits the curve?
(c) Will the car begin to slip before it exits the curve in this case above where the engine fails after 2.10 s?
