A race car starts from rest on a circular track of radius 378 m. The car's speed increases at the constant rate of 0.580 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

a)

b)

c)

Explanation:

From the question we are told that:

Radius

Acceleration

a)

Generally the  equation for speed of the car is mathematically given by

b)

Generally the  equation for distance traveled of the car is mathematically given by

c)

Generally the  equation for time of the car is mathematically given by

probably not if net force is zero
