PHYSÝCS HELP

A satellite with a mass of 113 kg approaches a large planet at a speed vi,1 =10.3 km/s. The planet is moving at a speed vi,2 =14.6 km/s in the opposite direction. The satellite partially orbits the planet and then moves away from the planet in a direction opposite to its original direction (see the figure). If this interaction is assumed to approximate an elastic collision in one dimension, what is the speed of the satellite after the collision? This socalled slingshot effect is often used to accelerate space probes for journeys to distance parts of the solar system.

Here’s the way this website works:
You post a question you have about your assignment, and then tell us what you think about it all so far. Then we can tell what help you need and work with you on your answers.
Please let us know what YOU THINK about solving YOUR problem  or what your question is about this assignment. 
ý don't know anything about physics and ý need to pass thýs lesson. ýf ý cant pass my schollarsýp ýs goýng to keep. please help

Here it is almost April, and you still don't know anything about physics? How's that skipping class working out for you?

apply the law of conservation of momentum, and the law of conservation of energy.
You will have two equations, two unknowns (V1', V2').
I recommend the method of substitution.
