A 3100 kg cannon is mounted so that it can recoil only in the horizontal direction.

(a) Calculate the magnitude of its recoil velocity when it fires a 14.0 kg shell at 480 m/s at an angle of 20.0° above the horizontal.

m/s

(b) What is the kinetic energy of the cannon? This energy is dissipated as heat in the shock absorbers that stop its recoil.
