an astronaut has a mass of 60 kilograms on earth. what would her mass be on mars? what would her weight be on mars? the strength of gravity o mars is 3.7 m/s^2....

Question

am having a slow moment, please help

Answer 1

Mass doesn't change. The astronaut's mass would remain 60kg on Mars.

Weight can be expressed as the force of an object due to gravity. Newton's second law described force being equal to mass x acceleration. Changing these terms to show weight (W) as force (measured in Newtons N), and acceleration as gravity (g), we can use the equation weight = mass x gravity, W=ma = (60kg)(3.7m/s^2)= 222 N
