In a 3-D computer game, a 5000-kg space probe in space (far from any significant interactions with planets or stars) has four thrusters that fire in the +x, –x, +y, and –y directions, respectively. As the space probe moves from to , there are two thrusters simultaneously firing with forces and respectively. If the initial speed of the space probe is 200 m/s, what is its final speed? State any assumptions that you make.
