Answer #1

work =mdg

       = 82.1 * 1910 * 9.81

       = 1538316 J

       = 1538.316 KJ

the work required to lift the person to the top of the mountain is 1538.316 KJ, we are making assumption that the work involved is climbing is four times this value

w = 4 * 1538.316 = 6153.26 KJ

2870 KJ energy from one mole of glucose then 6153.26 KJ of energy from = 6153.26/2870 = 2.14 moles

mass of 2.14 moles of glucose = 2.14* 180 = 385.2 grams.

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...

A mountain climber of mass m=75.0 kg slips during a climb and begins to fall freely. She forgot her rope and had to use an ideal spring. The spring is hanging vertically with an unstretched equilibrium position at the origin, x=0. On her descent, she grabs the end of the spring which has a spring constant of k= 981 N/m. Ignore friction, air resistance, and any other dissipative effects. a) The climbers velocity when she grabbed the spring was 20.0...
