(a) True, when an object is thrown vertically up in the air, its speed becomes zero at maximum height. However, it has acceleration equal to the acceleration due to gravity (g) that acts in the downward direction at that point.

When speed is zero, the magnitude of velocity along with the velocity is zero.

When speed is zero, the magnitude of velocity along with the velocity is zero.(c) Speed is the magnitude of velocity. Constant speed does not imply constant velocity as direction change may happen. Such a scenario is uniform circular motion of a particle about a center. In such a case, acceleration is not zero.
