When an 86.0 kg adult uses a spiral staircase to climb to thesecond floor of his house, his gravitational potential energyincreases by 1.70 x 10 to the 3 Joules. By how much does thepotential energy of a 24.0 kg child increase when the child climbsa normal staircase to the second floor?

a 245-kg boulder is dropped into a mine shaft thats is 3.0x10^3 m deep. During the boulder's fall, the system consisting of the earth and boulder loses a certain amount of gravitational potential energy. it would take an equal amount of energy to "free" the boulkder from the shaft by raising it back up to the top, so this can be considered the system's binding energy (a) determine the binding energy in joules of the system and (b) how much mass does the system lose when the boulder falls to the bottom of the shaft?

13.68 . A rocket with mass 5.00 X 10² kg is in a circular orbit of radius 7.20 x 10 m around the earth. The rocket's engines fire for a period of time to increase that radius to 8.80 X 100 m, with the orbit again circular. (a) What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decrease? (b) What is the change in the rocket's gravitational potential energy? Does the potential energy increase or decrease? (c) How much work is done by the rocket engines in changing the orbital radius?
