Question

Block B is moving towards right with a constant velocity 30m/s. Velocity of Block A with respect
to block B will be............m/s​

Answer 1

Answer:

Explanation:

sum of change in length = 0

suppose block a moves a rightwards

3v=2a

3v/2 = a

velocity of block a with respect to b will be = 3v/2-v = v/2
