Questions
Two balls A and B of same mass and a third ball of mass M are arranged over a smooth horizontal surface as shown in fig.(1) Ball A moves with a velocity v1
towards ball B and C. All collisions are assumed to be elastic. lf. m>M , the number of collisions between B and C
detailed solution
Correct option is A
The first collision will be between balls, A and B. In this collision ball A will come to rest while ball B will move forward with velocity v1 . This ball B will strike ball C (at rest). Let v2 and v3 be the speeds of ball B and ball C respectively after collision. We have v2=m−Mm+Mv1 and v3=2mm+Mv1 when MTalk to our academic expert!

Two identical balls B and C, in contact with each other and at rest on a horizontal friction less table, are hit head-on by another identical ball A moving initially with a speed v as shown in fig. (3). What is observed, if
the collision is elastic ?
