In the movie Monty Python and the Holy Grail, a cow is catapulted from the top of a castle wall over to the people down below. The gravitational potential energy is set to zero at ground level. The cow is launched from a spring of spring constant 1.6 X 104 N/m that is pulled back 0.3 m from equilibrium. If the castle is 9.6 m tall and the mass of the cow is 140 kg, what are the following? (a) the gravitational potential energy (in J) of the cow at the top of the castle J (b) the elastic spring energy (in J) of the cow before the catapult is released J (c) the speed (in m/s) of the cow right before it lands on the ground m/s
