Center of MassHard
Question
A ball of mass ′m′, moving with uniform speed, collides elastically with another stationary ball. The incident ball will lose maximum kinetic energy when the mass of the stationary ball is
Options
A.m
B.2m
C.4m
D.infinity
Solution
If mass = m
first ball will stop ⇒ v = 0
so k.e. = 0 (min)
In other cases then will be same
k.e. (k.e. can′t be negative)
first ball will stop ⇒ v = 0
so k.e. = 0 (min)
In other cases then will be same
k.e. (k.e. can′t be negative)
