Question

A car is traveling at a constant speed of 55k/h on a circular track. Is the car accelerating, explain

Answer 1

Answer:

Nope car is not accelerating

since it's mentioned that car is having const."speed"not velocity

Answer 2

Answer:

Yes, it is impossible to go around the curved path with zero acceleration. Acceleration is change in velocity. And velocity( speed+ direction) changes at every point in a curved path because there is change in direction at every point.

Explanation: an accelerating object is an object that is changing its velocity. And since velocity is a vector that has both magnitude and direction, a change in either the magnitude or the direction constitutes a change in the velocity. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.
