[ Multiple choices: (5 pts each_ 10 pts in total)) The mass of an astronaut is [80 lbs on the surface of the earth. What will his mass be on a planet where the gravitational acceleration is 2 m/s^2? A) 81.8 kg B) 164 kg C) 300 kg D) 360 kg Following question #1, what will his weight be on the planet? A) 642 N B) 360 N C) 8317 N D) 164 N

Step 1
81 m/s² = 784.8 N So, on the new planet, the mass of the astronaut will be: mass = weight / acceleration due to gravity = 784.8 N / 2 m/s² = 392.4 kg Show more…
