An astronaut weighs 104 newtons on the moon, where the strength of gravity is 1.6 newtons per kilogram. a. what is her mass? b. what is her weight on earth? c. what would she weigh on mars?

a) 65 kilogram

b) 637 newton

c)  242 newton

Explanation:

a)  1.6 newton is equivalent to 1 kilogram mass so

     104 newton will be equivalent to 104 / 1.6 = 65 kilogram

b) her weight on the earth = mass x gravitational acceleration

 = 65 x 9.8 = 637 newton

c) gravitational acceleration on the mars is 3,72 m per second squire so

 weight on mars = 65 x 3.72 = 242 approx.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
