The velocity of a projectile at the initial point A is `(2hati+3hatj) m//s`. Its velocity (in m/s) at point B is

`-2hati-3hatj`

`-2hati+3hatj`

`2hati-3hatj`

`2hati+3hatj`

Text Solution

Verified by Experts

The correct Answer is:

From the figure, the X-component remains unchanged while theY-component is reverse. Then, the velocity at point B is `(2hati-3hatj)m//s`.
