Question
Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed V as shown in figure (i). If the collision is elastic, which of the following is a possible result after collision?
Options
A.
B.
C.
D.
Solution
Sol. Momentum of first ball bearing is transfer to second & this momentum is finally transfer to 3rd.
Ball bearing (see “Newton’s cradle’ for details)
