Questions
If an ivory ball of mass 2m moving with a velocity 'v' strikes head on to a close row of three identical ivory balls each of mass m as shown in the figure. Then after the collisions which may be assumed as elastic, which of the following would occur?
detailed solution
Correct option is A
In option (1), final momentum of the system = mv + mv = 2mv. Initial momentum of the system = 2m x v = 2mvInitial energy of the system Final energy of the system Therefore Linear momentum and energy, both are conserved.Talk to our academic expert!
