1. The problem statement, all variables and given/known data A projectile launched vertically from the surface of the Moon rises to an altitude of 370 km. What was the projectile's initial speed? 2. Relevant equations h = 370,000 m g moon = 1.62 m/s^2 G = 6.67x10^-11 N m^2/kg^2 Mass moon = 7.35x10^22 kg Radius moon = 1.74X10^6 m vf^2 = vi^2 - 2gh 3. The attempt at a solution I calculated g on the moon to be 1.62 m/s^2. I then used kinematics (vf^2 = vi^2 - 2gh) and I get: vf = 0 vi = ? g = 1.62 m/s^2 vf^2 = Vi^2 - 2gh solving for Vi = sqroot of Vf^2 + 2gh I get initial velocity to be 1095.57 m/s. The answer is not correct, and I really don't understand what I'm doing wrong.
