A cannon is fired horizontally from a platform (Fig. P2.49). The platform rests on a flat, icy, friction less surface. Just after the shell is fired and while it is moving through the barrel of the gun, the shell (mass 3.2 kg) has an acceleration of +2500 m/s². At the same time, the cannon has an acceleration of -0.76 m/s². What is the mass of the cannon?
