A shell of mass 100kg is fired at an angle of 60 degree with the horizontal and with a velocity of 100m/s. The shell exploded into 3 fragments A, B, C at the highest point of the path. C of mass 40kg moved vertically up through 600m. B of mass 30kg moved horizontally, velocity being Vb. A of mass 30 kg moved obliquely downward, with a velocity Va. The point on the ground directly below the point of explosion is O. B landed at a distance of 600m from O. A and B both moved in the direction of the shell. (i) Calculate the horizontal distance traversed by A. (ii) Energy released due to the explosion.
