One of your summer lunar space camp activities is to launch a 1030 kg rocket from the surface of the Moon. You are a serious

science physics

Answer 1

Answer #1

here,

mass of rocket , m = 1030 kg

altitude , A = 219 km = 2.19 * 10^5 m

mass of Moon , M = 7.36 * 10^22 kg

radius of moon , R = 1740 km

R = 1.74 * 10^6 m

the gain in gravitational potential energy , PE = G * M * m * ( - 1/(R + A) - ( -1/R))

PE = 6.67 * 10^-11 * 7.36 * 10^22 * 1030 * ( - 1/(1.74 * 10^6 + 2.19 * 10^5) - ( -1/(1.74 * 10^6)))

PE = 3.25 * 10^8 J

the gain in gravitational potential energy is 3.25 * 10^8 J
