A racing car travels on a circular track of
radius 208 m. The car moves with a constant
linear speed of 26.3m/s.
A) Find its angular speed. Answer in units of rad/s. (0.126 rad/s is the answer)

I need help finding B

B) Find the magnitude of its acceleration. Answer in units of m/s^2

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

DATA:

Radius= 208m

Constant linear speed= 26.3m/s

Angular speed= ?

SOLUTION:

Angular speed = linear speed/radius

  = 26.3/208

  = 0.1264rad/s

FOR ACCELERATION

As the speed of the car is constant, so it means there is no change in the speed and in uniform speed the acceleration is equal to zero (0m/s2 ) because acceleration is define as "rate of change of velocity of an object."


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