A race car starts from rest on a circular track of radius 445 m. The car's speed increases at the constant rate of 0.380 m/s2. At the point where the magnitudes of the centripetal and tangential accelerations are equal, find the following.

(a) the speed of the race car

(b) the distance traveled

( c) the elapsed time
