4. 610 points 1 Previous Answers SerPSE9 6.P.006.w My Notes Ask Your 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 254 m and the car completes the turn in 35.0 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 m/s2 j (b) Determine the car's average speed m/s 7.26 (c) Determine its average acceleration during the 35.0-s interval. 0.267 Does the x component of the velocity increase or decrease during this time interval? What does this tell you about the sign of the x component of the acceleration? m/s2 + 0.203 x You can determine the y component of the average acceleration by considering only the y components of the initial and final velocities. m/s2 j Need Help?

Explanation / Answer

Doing part c

Speed=254/35=7.26 m/s

Average accleration=(final velocity-initial velocity)/time

Average accleration=(7.26j-7.26i)/35=0.207j-0.207i

Magnitude=0.293 m/s2
