A person is about to fire an arrow straight into the sky.
A - If the bow has a spring constant of 10 N/m and the bow is extended by 30 cm, what is the elastic potential energy of the bow just before it is released?
B - If all of this energy is transferred into gravitational potential energy, what is the maximum height that the arrow will reach if it has a mass of 120 g?
C - After the arrow has reached its maximum height, it turns and comes back down to Earth, calculate the maximum velocity that the arrow can hit the Earth with
