The moon has a mass of about 7.3x1022kg amd a radius of1738km.
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 ofthe moon at a speed of 1500m/sec. Using conservation of mechanicalenergy, compute the maximum distance reached by the spacecraft, atwhich the spacecraft comes to a stop.
c) if the spacecraft is launched with an initial speed of 5500m/secfrom the surface of the moon, use conservation of mechanical energyto determine how fast the spacecraft will be traveling when it isvery far from the moon.
