Question

A race car starts from rest on a circular track of radius
400 m. The car’s speed increases at the constant rate of
0.500 m/s2. At the point where the magnitudes of the
centripetal and tangential accelerations are equal, determine
(a) the speed of the race car, (b) the distance traveled,
and (c) the elapsed time.

Answer 1

Centripetal acceleration a= v^2 / r = 0.500 m/ s^2

Answer 2
