  1. The velocity of a projectile at the initial point A is ( 2î - 3ĵ )m/s. It’s velocity (in m/s) at point B is​​​​

    1. -2î + 3ĵ
    2. 2î - 3ĵ
    3. 2î + 3ĵ
    4. -2î - 3ĵ
Correct Option: B

At point B the direction of velocity component of the projectile along Y - axis reverses. ​
Hence, VB = 2î - 3ĵ
