A race car accelerates uniformly from a speed of 40 m/s to a speed of 60 m/s in 5 s while traveling counterclockwise around a circular track of radius 400 m. When the car reaches a speed of 50 m/ s, calculate: (i) the magnitude of the car's centripetal acceleration. (ii) angular speed (iii) magnitude of the tangential acceleration (iv) magnitude of the total acceleration.

Question
A race car accelerates uniformly from a speed
of 40 m/s to a speed of
60 m/s in 5 s while traveling
counterclockwise around a circular track of
radius 400 m. When the car reaches a speed
of 50 m/s, calculate:
(i) the magnitude of the car's centripetal
acceleration.
(ii) angular speed
(iii) magnitude of the tangential acceleration
(iv) magnitude of the total acceleration.
