Escape velocity is a measure of how fast an object must be moving
to escape the gravitational pull of a planet or moon with no further thrust. The escape
velocity for the moon is given approximately by the equation
V=5600
1000
distance from the center of the moon (in miles). If a lunar lander thrusts upwards until it
reaches a distance of 16,000 miles from the center of the moon, about how fast must it be
going to escape the moon's gravity?
