Question
A ball of mass 1 kg is thrown up with an initial speed of 4 m/s. A second ball of mass 2 kg is released from rest from some height as shown in the figure
- The centre of mass of the two balls comes down with acceleration g /3.
- The centre of mass first moves up and then comes down
- The acceleration of the centre of mass is g downwards
- The centre of mass of the two balls remains stationary.
The correct answer is: The centre of mass first moves up and then comes down

Figure shows a block P of mass m resting on a horizontal smooth floor at a distance l from a rigid wall. Block is pushed toward right by a distant 
and released. When block passes from its mean position another block of mass m1 is placed on it which sticks to it due to friction so that the combined block just collides with the left wall.
