Suppose you are driving a car in a counterclockwise direction on a circular road whose radius is r = 410 m (see the figure). You look at the speedometer and it reads a steady 32.9 m/s, (a) What is the angular speed of the car? (b) Determine the acceleration (magnitude and direction) of the car. (c) To avoid a rear end collision with the vehicle ahead, you apply the brakes and reduce your angular speed to 4.92 x 10 2rad/s in a time of 4.05 s. What is the tangential acceleration (magnitude and direction) of the car? IT (decreating) (al) Constant angular speed (b) Decreasing angular speed (a) Number Units (b) Direction Number Units (c) Direction Number Units
