Car A travels at a constant speed of 20 ms. Car8starts at rest and speeds up with conistant tangential acceleration untll its speed is 40 ms When car B has the same (tangential) velocity as car A it is always true that o it is passing car A o it has the same linear (tangential) acceleration as car A O it has the same total acceleration as carA has traveled farther than car A since starting. o it has the same centripetal acceleration as car A Moving to another question wil save this response. Question 140, 20 Pgup Home FS 5 6 8 2

Explanation / Answer

It has the same centripetal acceleration as car A.

because, a_centripetal = v^2/R

here v is speed of the car and R is the radius of the circular track.

when v is same for both cars, both cars will have same centripetal acceleration.
