Momentum and CollisionHard
Question
Consider an one dimensional elastic between a given incoming body A and B, initially at rest. The mas of B in comparison to the mas of A in order that B order that B should recoil with greater kinetic energy is
Options
A.mB >> mA
B.mB << mA
C.mB = mA
D.can′t say anything
Solution
Velocity of block B after collision v2 =
KE of block B =
mBv22 = 
mB 
Which is maximum if mA = mB
