A 3450 kg cannon is mounted so that it can recoil only in the horizontal direction. (a) Calculate its recoll velocity in m/s when it fires a 16.0 kg shell at 480 m/s at an angle of 20.0° above the horizontal. (Enter the magnitude.) m/s (b) What is the kinetic energy of the cannon in J? This energy is dissipated as heat transfer in shock absorbers that stop its recoil. (c) What happens to the vertical component of momentum that is imparted to the cannon when it is fired?
