Detailed Solution

The shape of the trajectory of the motion of an object is not determined by the acceleration alone but also depends on the initial conditions of motion (initial position and initial velocity). If initial velocity and acceleration are parallel then trajectory is a straight line, but if the initial velocity vector makes an angle with acceleration vector then the trajectory will be a parabola .
