A railway flat car has an artillery gun installed on it. The combined system has a mass `M` and moves with a velocity `V`. The barrel of the gun makes an angle a with the horizontal. A shell of mass `m` leaves the barrel at a speed `v` relative to the barrel. The speed of the flat car so that it may stop after the firing is

A car has a gun mounted on it. The combined system has a mass 10m and moves with a velocity V. The barrel of the gun makes an angle 37° with the horizontal. A shell of mass m leaves the barrel at a speed 50 m/s relative to barrel in the forward direction. The speed v of the car so that it may stop after the firing is

A railway flat car, whose mass together with the artillery gun is M, moves at a speed V. The gun barrel makes an angle with the horizontal. A shell of mass m leaves the barrel at a speed v, relative to the barrel. The speed of the flat car in order that it may stop after the firing is

A railway flat car, whose mass together with the artillery gun is M = 2 m , moves at a speed V . The gun barrel makes an angle alpha = 60^(@) with the horizontal. A shell of mass m leaves the barrel at a speed v = 12 ms^(-1) , relative to the barrel. Find the speed of the flat car V (in ms^(-1) ) in order that it may stop after the firing.
