Three objects `A` ,` B` and `C` are kept in a straight line on a smooth horizontal surface. These have masses `m `, `2m` and `3 m` , respectively . The head - on elastic collision takes place between `A` and `B` and then `B` makes completely inelastic collision with `C`. All motions occur on the same straight line. The final speed of `C` will be

There object A ,B and C are kept is a straing line a frictionless horizontal surface . These have masses have increase on 2m and m respectively . The object A move toward B with a speed 9 m//s and makes as elastic collision with a there after B makes completely inclesis with C . All motion over on the same straight line . Find the first speed of the object C

There object A ,B and C are kept is a straing line a fritionlas horizental surface . These have masses have increase on 2m and m repectively . The object A move toward B with a speed 9 m//s and makes as electic collision with a there after B makes complately inclesis with C . All motion over on the same strangth line . Find the first speed of the object C

A and B ---- rarr Elastic collision B and C ---- rarr inelastic collision. Find final speed of C

A particle of mass m_(1) moving on a smooth surface with some velocity strikes another particle of mass m_(2) at rest. The head - on elastic collision takes place. After the collision , particles move with equal speed in opposite direction . Determine the mass ratio.

An object of mass m is moving with velocity ữ towards a plane mirror kept on a stand as shown in the figure. The mass of the mirror and stand system is m. A head- on elastic collision takes place between the object and the mirror stand the velocity of image before and after the collision is
