A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure. The length of the arc ABC is 270 m, and the car completes the turn in 31.0 s.

(a) Determine the car's speed.
  m/s

(b) What is the magnitude and direction of the acceleration when the car is at point B?
magnitude       
Your response differs from the correct answer by more than 10%. Double check your calculations. m/s2

Explanation & Answer

Thank you for the opportunity to help you with your question!

a) speed=270/31=8.7097m/s

b) acceleration=velocity/distance

=8.7097/270

=0.0322 m/s^2

direction: 

=s/r

=(270/r)° 

Please let me know if you need any clarification. I'm always happy to answer your questions.
