A heavy dart and a light dart are launched vertically by identical ideal springs. Both springs were initially compressed by the same amount. There is no significant air resistance. Which of the
Following statements about these darts are correct? (There could be more than one correct choice.)
A) The light dart goes higher than the heavy dart.
B) At the maximum height, both darts have the same gravitational potential energy.
C) Both darts began moving upward with the same initial speed.
D) The heavy dart goes higher than the light dart.
E) Both darts reach the same maximum height.

Question

A) The light dart goes higher because, for a given amount of energy provided by the spring, a lighter object will achieve a higher velocity and thus a higher maximum height due to the conservation of energy principle. B) At the maximum height, both darts have the same gravitational potential energy because the energy transferred from the spring to each dart is the same initially, and without air resistance, energy conservation ensures that all this energy is converted into gravitational potential energy at the maximum height.
