Homework Statement
A projectile of mass m is fired from the surface of the Earth at an angle α from the vertical, where α = 0.34 radians. The initial speed v0 is equal to √{GM/Rearth}. Calculate the maximum height that the projectile will reach. Neglect air resistance and the Earth's rotation. Express the result as the ratio to the radius of the Earth.
Homework Equations
U_G=(GMm)/R
KE=.5mv02
The Attempt at a Solution
So i believe that the fact that it is fired at an angle is irrelevant because Earth's gravitational field is in all directions.
Then i just equated the energy equations and solved for R, however this did not yield the correct answer. THoughts?
