Question: A car initially traveling eastward turns north by
A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in Figure P6.10. The length of the arc ABC is 235 m, and the car completes the turn in 36.0 s. (a) What is the acceleration when the car is at B located at an angle of 35.0°? Express your answer in terms of the unit vectors i and j. Determine (b) The car’s average speed and (c) Its average acceleration during the 36.0-s interval.
