Q21 Two blocks M and M having equal mass are free to move on a horizontal frictionless surface M is attached to a massless spring as shown in figure Initially M is at rest and A is moving toward M with speed v and collides head on with M a While spring is fully compressed all the KE of Myis stored as PE of spring b While spring is fully compressed the system momentum is not conserved though final momentum is equal to initial momentum c If spring is massless the final state of the M is state of rest d If the surface on which blocks are moving has friction then collision cannot be elastic M m M m V rw
