A stopwatch starts while race car travels at 6 m/s from the pit area and accelerates at a uniform rate to a speed of 38 m/s in 7 s moving on a circular track of radius 524 m.
Assuming constant tangential acceleration, find
(a) the tangential acceleration, and
(b) the radial acceleration,at the instant when the speed is v = 6
Once you have both of those. Find the magnitude of a at any moment
