1. Find the velocity of escape of the Apollo spaceship as it is projected from the earth's surface, that is the minimum velocity imparted to it so that it will never return. The radius of the earth is 4000 miles and the acceleration of the spaceship is 32.2 ft/sec. (Express your answer in kph) Hint: v = /2gR ; 1 mi = 5280 ft = 1.61km
