13.153 An old 3000-lb cannon fires an 18-lb shell with an initial velocity of 1500 ft/s at an angle of 30° (you may assume this is the absolute velocity of the shell). The cannon rests on a horizontal surface and is free to move horizontally. Assuming that the barrel of the cannon is rigidly attached to the frame (no recoil mechanism) and that the shell leaves the barrel 5 ms after firing, determine (a) the recoil velocity of the cannon, (b) the resultant of the vertical impulsive forces exerted by the ground on the cannon.
