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 explosion?

Options

A. II,IV,V
B. I,III,VI
C. I,III,V
D. II,III,VI

Answer

A

Explanation

Physically possible exposions are those in which both particles move in possible direction i.e., signs of velocities are opposities
`implies II,IV and V`
