The velocity of a projectile at the initial point A is $(2\hat{\mathbf{i}}+3\hat{\mathbf{j}})$ ms^-1. Its velocity (in ms^-1) at point B is          

• A

  $-2\hat{\mathbf{i}}-3\hat{\mathbf{j}}$

• B

  $-2\hat{\mathbf{i}}+3\hat{\mathbf{j}}$

• C

  $2\hat{\mathbf{i}}-3\hat{\mathbf{j}}$

• D

  $2\hat{\mathbf{i}}+3\hat{\mathbf{j}}$
