While co-piloting a futuristic spacecraft, you receive a report of your position and velocity in the geocentric-equatorial frame

R = 7000 I + 0 J + 0 K km
V = 0 I -7.063 J + 0 K km/s


a. What is the specific angular momentum?

h = r * v
h = 7000 * (-7.063)
h = -49441
h = -49,441 K km^2/s


b. What does this angular momentum vector tell you about the orientation of your orbit?

**I NEED HELP ON THIS ONE (B)


c. What is your specific mechanical energy?

e = - (3.986 * 10^5 (km^3/s^2))/2a

** I NEED HELP HERE AS WELL!! (C)

I DO NOT KNOW HOW TO GET a


I know the answer is e = -31.99 km^2/s^2


d. What is the shape of your trajectory? How can you tell?

**AND I NEED HELP HERE PLEASE! (D)
