When an object of mass M and velocity u collides head-on elastically with a stationary object of mass m, show that mass m, moves off with velocity V2 given by:
V2 = (2M/M+m) u
I done:
Mu + m = MV1 + mV2
and making V2 subject of formula...
V2 = (Mu + m - MV1)/m
but from here got stuck.
any help will be appreciated.
+rep offered to most thorough answer.
Thanks!
