Last updated: 8/8/2022

A ball of mass 0.075 kg is fired horizontally into a ballistic pendulum as shown in the figure above. The pendulum alone has a mass of 0.350 kg. The ball is caught in the pendulum, and the center of mass of the system rises a vertical distance of 0.145 m. (a) What is the initial speed of the ball? (b) What is the speed of the pendulum immediately after it catches the ball? (c) Find the kinetic energy loss due to the collision. Assume that g = 9.80! m/s². Show your work.
