Question

The Velocity of Particle A with respect to ground is (2i - j) m/s and the velocity of B with respect to ground is (-2i - 3j) m/s. the velocity of A with respect to ground is :-

1. (4i + 2j) m/s.
2. (-4i - 2j) m/s.
3. -4 j m/s
4. 4i + 3j m/s.

Answer 1

Answer:

Velocity of A wrt B = $V_{AB}$ = $V_{A}$ - $V_{B}$ = (4i + 2j) m/s

Explanation:

Given :

Velocity of A wrt ground $V_{A}$ = (2i - j)   m/s

Velocity of B wrt ground $V_{B}$ = ( - 2i - 3j)  m/s

Velocity of A wrt B = $V_{AB}$ = $V_{A}$ - $V_{B}$ = (4i + 2j) m/s
