A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure below. The length of the arc ABC is 257 m, and the car completes the turn in 37.0 s. y (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. 2105 First find the magnitude of the acceleration; then work out the components of the vector. m/s2 T + \\:I m/s? (b) Determine the car's average speed. s (c) Determine its average acceleration during the 37.0-s interval. [ Jmsie e Need Help? [ mman ] (-]
