A railway flat car has an artillery gun installed on it and contains shells for firing The combined system excluding shell has a mass M and moves with a velocity v 0 . The barrel of the gun makes an angle α = 60° with the horizontal. A shell of mass m leaves the barrel at a speed u = 40m/s relative to initial state of barrel in the forward direction. The speed of the flat car so that it may stop after the firing is: (neglect friction) Given : M = 10m

(2)
u - velocity of shell with respect to gun.
In horizontal direction 
= 0, so centre of mass move with constant velocity in horizontal plane.
(M + m)v 0 = m(v 0 + u cos α )
V 0 =
