A person of mass 75 kg is standing on the surface of the Earth. a. Calculate the total energy of this individual, assuming they are at rest relative to the surface. (Hint: Use the expression for gravitational potential energy (*NOT Ug=mgh*)). Although the person is standing at rest relative to the surface of the Earth, they are rotating along with the Earth and thus store some kinetic energy.) Ignore the rotation of the Earth about the Sun, the motion of...
