In 2286, Admiral Kirk and his crew were forced to use the slingshot effect in a stolen Klingon Bird-of-Prey to travel back in time to the late 20th century to retrieve two humpback whales. The stolen Klingon Bird-of-Prey traveled towards the sun at a velocity of vs while the sun was moving towards them at a velocity of u, then traveled around the sun (using the sun's gravitational field) such that stolen Klingon Bird-of-Prey was now moving in the opposite direction from whence it started, with a new velocity, vnew. Find vnew in terms of u and v,assuming the mass of the sun is much larger than the mass of the spaceship
