At the end of a rocket launch of a space vehicle from a launch site on the earth’s equator, the following burnout conditions hold. the burnout altitude is 110 km, and the burnout velocity vector lies in the equatorial plane with magnitude 8.3 km/s and flight path angle of 3 degrees above the local horizontal.

after burnout, the space vehicle moves along a two-body orbit.

(a) what is the specific angular momentum of the orbit of the space vehicle? what is the specific total energy of the orbit of the space vehicle?

(b) what is the orbital eccentricity?

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
