Which graphs pertain to physically possible explosions –

Question

An initially stationary box on a frictionless floor explodes into two pieces, piece A with mass m_A and piece B with mass m_B . Two pieces then move across the floor along x-axis. Graph of position versus time for the two pieces are given.

Which graphs pertain to physically possible explosions – 

(a) II, IV and V 

(b) I, III, VI 

(c) I, III, V 

(d) II, III, VI

Answer 1

Correct option: (a) II, IV and V

Explanation:

Physically possible explosions are those in which both particles move in opposite directions. i.e. signs of velocities are ⇒ II, IV & V
