    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 \[\left( \text{2i-3j} \right)\text{ ms}{{\text{-}}^{\text{1}}}\].
