(a) A constant force < 31, -13, 36 > N acts through a
displacement < 0.17, 0.34, -0.24 > m. How much work does this
force do?
Work =
?J
(b) An object with mass 7 kg moves from a location < 28, 28, -43
> m near the Earth's surface to location < -34, 16, 45 >
m. What is the change in the potential energy of the system
consisting of the object plus the Earth?
Change of potential...
