Question

(4) How much work (in Joules) is done on a 1kg object to lift it from the center of the Earth
to its surface? The gravity force in Newtons on a 1 kg object at distance r from the
center of the Earth is given by:
F(r) = 0.0015r.
The radius of the Earth is R = 6, 371km.

1. The Hubble space telescope orbits the Earth at an altitude of approxi- mately 600 kilometers and has a mass of 1.11 × 104 kg. (a) be pulled down to the surface of the Earth. Ignoring all air resistance, determine the speed with which the telescope would impact the Earth. Use mgh as the gravitational potential energy, where m is the mass of the telescope, g = 9.81 m/s? (the acceleration due to gravity at the surface of the Earth), and h is the distance the Hubble space telescope were to come to an abrupt stop it would above the surface of the Earth. (b) gravitational potential energy, Ug = -GmM/r, where G is Newton's gravitational constant, m is the mass of the telescope, M is the mass of the Earth, and r is the distance from the center of the Earth to the Hubble telescope. Repeat the calculation from Part (a) using the actual expression for the
