Object A has 604 J of kinetic energy and 285 J of gravitational potential energy. Object B has 481 J of kinetic energy and 300 J of gravitational potential energy. Which object has more mechanical energy?

Mechanical energy is the sum of kinetic energy and gravitational potential energy. Object A has 604 J + 285 J = 889 J, while object B has 481 J + 300 J = 781 J. Since 889 J is greater than 781 J, Object A has more mechanical energy.
