2. Justin is driving at a constant velocity of 22.6 m/s eastbound in his 945-kg car on a rough road. Suddenly, he sees a raccoon in the street, so he slams on the brakes. His brakes exert a force of
100 N on the wheels.

a. Draw and Label a FBD before the brakes are applied.

b. Calculate the net force

C. Calculate the acceleration of the car once the brakes are applied.

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion
