A projectile launched vertically from the surface of the Moon rises to an altitude of 270 km. What was the projectile's initial speed in m/s? okay so I keep getting this answer wrong but Im pretty sure Im doing it correctly..... this is what I am doing: 2*6.67*7.35*270/3.02 and then all of that multiplied by 10^2 and then that answer square rooted and I get 936.27 m/s .....but that is not correct...HELP! what am I missing??
