Answer: 44.98 pounds

Step-by-step explanation:

Weight = mass * acceleration due to gravity

acceleration due gravity (earth) = 9.8 m/s²

Astronaut weight on earth =

W = M * g =》 150 = Mass * 9.8

Mass of the astronaut = 150 / 9.8 = 15.306 pound

His weight in Jupiter became 400 pounds

Acceleration due to gravity on Jupiter?

W = m * g

400 = 15.306 * g

g = 400 / 15.306

g = 26.13 m/s

Acceleration due to gravity on Jupiter = 26.13 m/s

Weight of the alien = 120 pounds

Mass of the alien?

W = m * g

120 = mass * 26.13

Mass = 120 / 26.13 = 4.59 pounds

Weight of the alien on earth = mass * acceleration due to gravity (earth)

W = 4.59 * 9.8

W = 44.98 pounds
