Answer»

Correct answer is (b) Uniformly accelerated

The best explanation: The three equations of motion are valid for uniformly accelerated motion. The equations do not WORK in situations where the acceleration is non-uniform. In that case it is better to work with the DIFFERENTIAL FORMS of velocity and acceleration.
