3. Now you drive clockwise around the track again. This time, as you drive the large arc (radius 30 m), you speed changes uniformly from 7 m/s to 13 m/s in 2 seconds. a. What is your tangential acceleration in this turn? b. What is your centripetal acceleration at point (Y) when your speed is 10 m/s? Y c. What is the magnitude of your acceleration at this point? d. Draw an arrow at (Y) indicating the direction of the acceleration at that point. What is the angle between the direction of the velocity and acceleration vectors at that point?
