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.
J
(c) What happens to the vertical component of momentum that is imparted to the cannon when it is fired?
A dare devil is shot out of a cannon at 45.0 degrees to the horizontal with an initial speed of 25.0 m/s. A net is positioned a horizontal distance of 50.0 m from the cannon.
