Problem: In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0255 kg and the mass of the pendulum is 0.250 kg,
Part A: How high will the pendulum swing if the marble has an initial speed of 5.65 m/s?
I need help to solve the above question and assume that the mass of the pendulum is concentrated at its end.
