12. Escape Velocity To escape Earth's gravitational field, a rocket must be launched with an initial velocity called the escape velocity. A rocket launched from the surface of Earth has velocity v (in miles per second) given by V = 2GM Tº + v² - 2GM R where vo is the initial velocity, r is the distance from the rocket to the center of Earth, G is the gravitational constant, M is the mass of Earth, and R is the radius of Earth (approximately 4000 miles). V= a. Find the value of vo for which you obtain an infinite limit for r as v approaches zero. This value of vo is the escape velocity for Earth. 192,000 T b. A rocket launched from the surface of the moon has velocity v (in miles per second) given by V = 1920 T +v-48 + - 2.17. Find the escape velocity for the moon. c. A rocket launched from the surface of a planet has velocity v (in miles per second) given by 10,600 T + v² - 6.99.
