Answer:

Explanation:

A body has zero velocity and is still accelerating.

The velocity of an object reverses direction when acceleration is constant.

An object's speed goes on increasing even magnitudes of its acceleration decreases.

None of these

Solution :

(A) When the body is projected vertically up, at the highest point its speed becomes zero whereas it is accelerating downwards withg=9.8m/s2.

(B) When a body is projected up, the velocity at the highest point reverses its direction whereas the acceleration of the body remains constant, that is vevg.

(C) Acceleration means, increasing speed (magnitude of velocity). Therefore, the speed of a particel increases with an acceleration. When the acceleration is decreased the speed of the particle goes on increasing till the acceleration reduces to zero.
