Expert Solution

Explaination

Yes, it is possible. But not permenantly it happens momentarily.

Acceleration means change in velocity. since velocity is a vector quantity if acceleration acts in opposite direction of velocity, at particular point, velocity becomes zero while acceleration is non zero.

For example take projectile motion, in projectile motion at maximum height (peak) velocity is zero but the still acceleration due to gravity acting on projectile at that point.

And take basket ball for instance, when it comes down from ring and bounce back at highest point its velocity is zero but it have an acceleration of g = 9.8 m/s² at that point.
