a. on earth? (9.8m/s2)
b. on mars? (3.8 m/s2)
i need help on this phycics problem

Simple....
weight=mass x accn. due to gravity........
Weight on earth=Same as given i.e. 64 kg.
Weight on mars= (64/9.8) x 3.8=24.816 kg.
Here 64 kg is weight and not mass.
Mass of astronaut is = weight/accn. due to gravity

Try W= mg
U should be able to figure out what each letter stands for, hv u ever heard of a calculator, u can use it to solve simple qxns like this OR JUST READ UR TEXTBOOK.

#1) you spelt physics wrong
#2) this required about 30 seconds of research in your textbook to figure out how to do it. i'm annoyed, this is the simplest physics problem i've seen on answers in a very long time.

a) On earth-:
F = m a
F = 64 x 9.81 = 627.84 Newtons
b) Mars
F = m a
F = 64 x 3.8 = 243.2 Newtons

his weight(meaning the force that is applied on him by the planet)
a. On earth is 627.2N
b. On Mars is 243.2N
F = m*g (where F:weight, m:mass, g:gravity acceleration)
