| The velocity of a projectile at the initial point A is\[(2i+3j)\text{ }m/s\]. Its velocity (in m/s) at point B is [NEET 2013] |
 |
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 \[(2i-3j)\text{ }m{{s}^{-1}}\].
