A shell of mass m moving with velocity v
Asked by admin @ in Physics viewed by 295 People
a shell of mass m moving with velocity v suddenly break into two pieces the part having mass m/3 remains stationary. the velocity of other part will be
Answered by admin @
Momentum before breaking up is equal to momentum after breaking up. If mass of one of the fragments is m/3 then that of the other is (2/3)m So, mv = mv1/3 + (2/3)mv2
Given that mv1 = 0,
mv = 0 + (2/3)mv2
i.e. v = (2/3)v2
or v2 = (3/2)v
