The moon has a mass of about 7.3x1022kg amd a radius of 1738km.
a)Calculate the escape speed from the surface of the moon. Express the answer in km/sec.
b) A spacecraft of mass 250kg is launched from the surface of
the moon at a speed of 1500m/sec. Using conservation of mechanical
energy, compute the maximum distance reached by the spacecraft, at
which the spacecraft comes to a stop.
c) if the spacecraft is launched with an initial speed of 5500m/sec
from the surface of the moon, use conservation of mechanical energy
to determine how fast the spacecraft will be traveling when it is
very far from the moon.
comments
A) the escape speed of moon was found to be 2367.789 m/s.
B) the maximum height of the spacecraft was found to be 6.92*10^5 m.
C) the final speed of the space craft was found to be 5500 m/s.
