Which situation is impossible for a moving object at a given moment? a. the object has zero velocity but non-zero acceleration. b. the object has constant non-zero velocity and changing acceleration. c. the object has constant non-zero acceleration and changing velocity. d. the object has velocity directed east and acceleration directed west. e. the object has velocity directed east and acceleration directed east.

B. The object has constant non-zero velocity and changing acceleration.

Explanation:

Acceleration is defined as the rate of change in velocity of object

so whenever object is in accelerating mode then its velocity may have any magnitude and any direction

but the velocity will change at every moment of time

so it can not have uniform velocity when object has non zero acceleration

so here correct answer will be

B. The object has constant non-zero velocity and changing acceleration.

explanation:

newton's third law, for every action there is an equal and opposite reaction.

d. air pressure decreases as altitude increases.
