1. A stopwatch starts while race car travels at 7 m/s from the pit area and accelerates at a uniform rate to a speed of 30 m/s in 19 s moving on a circular track of radius 511 m. Assuming constant tangential acceleration, find
(a) the tangential acceleration, and
(b) the radial acceleration, at the instant when the speed is v = 15
Once you have both of those ... find the magnitude of a at any moment

2. A stopwatch starts while race car travels at 12.0 m/s from the pit area and accelerates at a uniform rate to a speed of 33 m/s in 16 s moving on a circular track of radius 502 m.
Assuming constant tangential acceleration, find
(a) the tangential acceleration, and
(b) the radial acceleration, at the instant when the speed is v = 17
Once you have both of those ... find the magnitude of a at any moment

3. 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 25 m/s in 3 s moving on a circular track of radius 492 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
