Andee has a mass of 68.5 kg on earth. What is his weight on Earth? What should his mass be in order to have the same weight at the surface of the moon?
weight (force) = mg
Look up g if you don't know it.
Now, divide that by the relative gravity of the moon. For example, if the moon has 1/2 the gravity of earth, you will need double the mass for the same weight.
I have this assignment too right now,and can't answer it..because the gravity of earth in the moon is not given:(
W = mg
W = (68.5 kg) (9.8 m/s^2)
W = 671 N
m = W/g
m = 671N/9.8 m/s^2
m = 68.5 kg
Lols. Not really sure about the answer on the mass because there's no given gravity of the moon.
