**AP Review Problems – Resistive Forces as Functions of Velocity**

AP C 1993 A car of mass m, initially at rest at time t = 0, is driven to the right, as shown above, along a straight, horizontal road with the engine causing a constant force Fo to be applied. While moving, the car encounters a resistance force equal to ‑kv, where v is the velocity of the car and k is a positive constant. a. The dot below represents the center of mass of the car. On this figure, draw and label vectors to represent all the forces acting on the car as it moves with a velocity v to the right.
