Blocks A and B are resting on a smooth horizontal surface given equal speeds of `2ms^(-1)` in opposite sense as shown in the figure.

At t=0, the position of blocks are shown, then the coordinates of center of mass t=3s will be

A

(1,0)

B

(3,0)

C

(5,0)

D

(2.25,0)

Text Solution

Verified by Experts

The correct Answer is:
D
At t=0 center of mass is at mid-point or at (2.25m, 0). Velocity of center of mas is zero. Hence center of mass will remain at this position all the time.
