If anyone could help me with my homework I would GREATLY appreciate it. I am totally lost. There are 2 questions. If you could tell me what/how to do it, I'd be happy to do it. I just need to know how. Thanks so much Here is question 2: A 5.5 kg mass is dropped at a constant velocity thru a vertical displacement of 2.0 m over a time interval of 4.0 seconds. How much potential energy (joule) has it given up? What is the power (watt) output? If that power output was kept up for 24 hours how many kWhr of energy would be produced?
