A particle moves in a plane with constant acceleration in a direction different from the initial velocity. The path of the particle is

1. an ellipse
2. a parabola
3. an arc of a circle
4. a straight line

Correct answer: a parabola

Solution

When a particle moves in a plane with constant acceleration in a direction different from its initial velocity, the trajectory is a parabola. This is because the motion can be resolved into two components: one with constant velocity and the other with constant acceleration, leading to a parabolic path.
