- Two cars are moving in the same direction in parallel lanes along ahighway. At some instant, car A is traveling faster than car B. Does that mean the acceleration of A is greater than that of B at that instant? (a) Yes. At any instant, a faster object always has a larger acceleration. (b) No. Acceleration only tells how an object's velocity is changing at some instant.arrow_forwardA train, traveling at a constant speed of 22.0 m/s, comes to an incline with a constant slope.
