As shown in figure, two blocks are connected with a light spring. When spring was at its natural length, velocities are given to them as shown in figure. Choose the wrong alternative.

Options:

Answer:

Solution:

$v_{cm} = \frac{20 \times 6 - 10 \times 3}{20 + 10} = 3 m / s$ towards right. At the time of either maximum elongation or compression, both the blocks will be moving with a common velocity $= 3 m / s$ towards right.
