When it reaches the bottom of the ramp, it collideswith Box B(also with mass of 5 kg) attached to apendulum. There is Velcro on the boxes, so theycompletely stick together and swing out on thependulum’s rope. Remember: When a pendulumreaches its apex (maximum height), it momentarilycomes to a stop.1.Create an “Closed” Energy Interaction Diagram for
