Problem: Suppose that in your experiment with the ballistic pendulum the pendulum cage rose to a height H. Now suppose you repeated the experiment but this time you used a ball with twice the mass and the mass of the pendulum cage was increased to twice its original mass. However the spring launching the ball was adjusted so that the initial speed of the ball was the same as it was in your experiment.
Part A: What height would the pendulum cage rise to in the repeated experiment?
I need help to find what height the pendulum cage would rise to in the repeated experiment.
