Arace car starts from rest on a circular track of radius 310 m. its speed increases at the constant rate of 0.6 m/s 2 . at the point where the magnitudes of the radial and tangential accelerations are equal, determine the speed of the race car. answer in units of m/s

The speed of the race car is 13.63 m/s.

Explanation:

It is given that,

Radius of the circular track, r = 310 m

Acceleration of the car,

We need to find the speed of the race car. In circular motion, the object moves under the action of centripetal acceleration which is given by :

v = 13.63 m/s

So, the speed of the race car is 13.63 m/s. Hence, this is the required solution.

i guess it’s a and b
