A baby carriage that is carrying twins is sitting at the top of a knoll that is 21 m high. The carriage with the babies is 48kg. What is the Potential Energy of the twins and the carriage? i have to do it with Potential Energy = Weight x Height Weight = Potential Energy / Height

Height = Potential Energy / Weight

Weight = Mass x 10

Mass = Weight / 10
