A 85 kg man goes to Mars. The gravity on Mars is 3.7 m/s2. Which choice below is true about his mass and weight?
His mass will increase to 314.5 kg. His weight will not change.
Both his mass and weight will stay the same.
Both will increase. His new mass will be 314.5 kg. His new weight will be 314.5 N.
His mass will stay the same. His weight will become 314.5 N.
