    The velocity of a projectile at the initial point A is \[(2i+3j)\,m/s.\] Its velocity (in m/s) at point B  is

    A)  \[-2i-3j\]

    B)  \[-2i+3j\]

    C)  \[2i-3j\]

    D)  \[2i+3j\]

    Correct Answer: C

    Solution :

     From the figure the X-component remain unchanged, while the \[Y-\]component is reverse. Then, the velocity at point B is\[(2i-3j)m{{s}^{-1}}.\]
