Maximum energy loss will take place in perfectly inelastic collision, and is given by, ΔK=2mP2−2(m+M)P2
⇒ΔK=2mP2[1−(m+M)m]
⇒ΔK=2mP2[(m+M)M]
⇒ΔK=21mv2[(m+M)M]
On comparing with the given form of equation, we have, (f=m+MM)
Hence Statement-I is false, Statement-II is true. ( As it is perfect Inelastic collision)
