Answer:
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,
