Since the car is moving on a circular track with non-uniform speed, it is assumed required acceleration is total acceleration.

Total acceleration in this case is time dependent.

speed v at time t is given by, v = u + a t = 30 + (2)t

Hence radial acceleration, ar = (v2 / r) = (30+2t)2 /500 m/s2

Tangential acceleration at = 2 m/s2

Total acceleration, (SEE ATTACHMENT)

Explanation:

hope this should help out so angle would be cos inverse 12.5
