The Tower of Terror ride at Disney World can lift 12 people 60 meters into the air. If the engineers assume that the average person has a mass of 60 kg What is the potential energy of a single person at the top of the ride?

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
