A shell of mass 50 kg moving at the velocity 600 m/s gets into the platform with sand of mass 10 tones. The velocity of the shell is directed at the angle 45 to horizontal on the instant of its getting into the platform. Find the velocity of the platform if it was moving towards the shell at the velocity 10 m/s.
