- the trolley moves towards right
- the trolley rebounds with velocity
- the centre of mass of the system remains stationary
- all the above
The correct answer is: all the above

A block of mass m starts from rest and slides down a frictionless semi–circular track from a height h as shown. When it reaches the lowest point of the track, it collides with a stationary piece of putty also having mass m. If the block and the putty stick together and continue to slide, the maximum height that the block-putty system could reach is:
