The velocity of a projectile at the initial point A is `(2 hati +3 hatj) ms^(-1)`. Its velocity (in `ms^(-1))` at point B is

`2hati - 3hatj`

`-2hati +3 hatj`

`2hati - 3hatj`

`2hati +3hatj`

Text Solution

Verified by Experts

The correct Answer is:

From the question's figure, the X-component remain unchanged, while the Y-component is reverse. Then, the velocity at point B is `(2hati - 3hatj) ms^(-1)`.
