Momentum and CollisionHard
Question
Two blocks A and B are joined together with a compressed spring. When the system is released, the two blocks appear to be moving with unequal speeds in the opposite direction as shows in figure .
Options
A.The centre of mass of the system will remain stationary .
B.Mass of block A is equal to mass of block B.
C.The centre of mass of the system will move towards right.
D.It is an impossible physical situation.
Solution
As net force on system = 0 (after released)
So centre of mass of the system remains stationary .
So centre of mass of the system remains stationary .
