The velocity of a projectile at the initial point A is ($2\overbrace{\mathrm{i}}+3\overbrace{\mathrm{j}}$) m/s. Its velocity (in m/s) at point B is

 

• A

  $-2\overbrace{ \mathrm{i}}-3\overbrace{\mathrm{j}}$

• B

  $-2\overbrace{\mathrm{i}}+3\overbrace{j}$

• C

  $2\overbrace{\mathrm{i}}-3\overbrace{\mathrm{j}}$

• D

  $2\overbrace{\mathrm{i}}+3\overbrace{\mathrm{j}}$
