Two pendulums are set up side by side, and each of them has a different mass. Pendulum A has a mass of 60 g, and Pendulum B has a mass of 80 g. Both pendulums are suspended from the ceiling with strings that are each 40 cm long. Pendulum A is pulled away to form a 45° angle with the vertical and then is released. What is the speed of Pendulum A just before it impacts Pendulum B?
