Motion in A Plane
Question
Wired Faculty App

The velocity of a projectile at the initial point A is (2 i + 3 j) m/s. Its velocity (in m/s) at point B is,

  • -2 i - 3 j

  • -2 i + 3 j

  • 2 i - 3 j

  • 2 i + 3 j

Answer

C.

2 i - 3 j

From the fig,, the X component remain unchanged, while the Y-component is reverse. Then, the velocity at point B is (2 i - 3 j) m/s.
