These are the answers i got for the various questions using maths

projectile range: 220.92 m
mars mass: 7.35 x 10^22 kg
velocity of orbit: 1627.996 m/s

Option
Mass defect: 3.2 x 10^-28 kg
Energy released in equation: 2.9 x 10^-11 J
Wavelength of series: 4.9 x 10^-7 m
Energy of photon: 4.09 x 10^-19 J

for the velocity of orbit i got a different answer. i used square root GM/r tho....

 

[fush]

yea i used v = root GM/r but i cant remember what i got

i think i got 5.99 x 10^-1 :/

i think that would be way too slow for an orbit, its not even 1m/s?
