A rocket drifting sideways in outer spaces from position 'a' to position 'b' with constant velocity. At 'b' the rocket's engine starts to produce constant thrust at right angles to line 'ab'. The engine turns off again as the rocket reaches some point 'c'. Assume that rocket is subjected to no other forces.

Options

A. The path of rocket from point b to c will be
B. The path of rocket from point b to c will be
C. The path of rocket beyond c will be
D. The speed continuously increases from b to c.

Answer

B, C, D

Explanation

(B) Acceleration is upward with horizontal initial velocity so trajectory is parabolic.
(C) Acceleration is zero so velocity is constant.
(D) Due to acceleration speed increase
