Question

A projectile is fired from a gun on the ground angled up at 6 degrees.
The gun will give the projectile all of the necesary orbital velocity.

I need to know the delta-v that a thruster on the projectile would need for orbit insertion.
a) for a 300km circular orbit
b) for an elliptical orbit with a perigee of 300km, any apogee is ok.


No inclination change. Initial and final inclination is 15 degrees.
Total projectile mass is 500kg.
