उत्तर
The velocity of a projectile at the initial point A is `(5 hat "i" + 2 hat "j")` m/s. Its velocity (in m/s) at point B is `5 hat "i" - 2 hat "j"`.
Explanation:
Horizontal (X) component remains the same while the vertical (Y) component changes. Therefore, velocity at B = `(5 hat"i" - 2 hat"j")` m/s.
