Question
Two balls of same mass are doped from the same height onto the floor. The first ball bounces upwards from the floor elastically The second ball sticks to the floor The first applies an impulse to the floor of I1 and the second an impulse I2. The impulse obey
Options
A.I2 = 2I1
B.I2 = 
C.I2 = 4I1
D.I2 = 
Solution
mu - I1 = - mu ∴ I1 = 2mu &
mu - I2 = 0 ⇒ I2 = mu (for IInd ball) ∴ I2 = I1/2
mu - I2 = 0 ⇒ I2 = mu (for IInd ball) ∴ I2 = I1/2
