A race car starts from rest on a circular track of radius 404 m. The car's speed increases at the constant rate of 0.400 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
