Scientists are developing a new space cannon to shoot objects from the surface of the Earth di- rectly into a low orbit around the Earth. For testing purposes, a projectile is fired with an initial velocity of 2.8 km/s vertically into the sky. Calculate the height that the projectile reaches, . (a) assuming a constant gravitational deceleration of 9.81 m/s?. (b) considering the change of the gravitational force with height. Note: Neglect the air resistance for this problem. Use 6.67x10-1! m³kg-'s-2 for the gravitational constant, 6371 km for the Earth's radius, and 5.97 x 1024 kg for the Earth's mass.

Two satellites are in circular equatorial orbits of different altitudes. Satellite A is in a geosynchronous orbit (one with the same period as the earth's rotation so that it "hovers" over the same spot on the equator). Satellite B has an orbit of radius rg = 34 000 km. Calculate the velocity which A appears to have to an observer fixed in B when the elevation angle is (a) O and (b) 90°. The x-y axes are attached to B, whose antenna always points toward the center of the earth (-y-direction).

In his novel From the Earth to the Moon Jules Verne first suggested that it might be possible to travel to the moon by firing a very high velocity projectile at the moon. Find the minimum initial velocity of such a projectile as it leaves earth's atmosphere. Take into account the moon's gravitational force.
