A space probe in outer space has a mass of 111 kg, and it is traveling at a speed of 29 m/s. When it is at location 445, 535,
−350 m it begins firing two booster rockets. The rockets exert constant forces of 90, 150, 195 N, and 90, −90, −585
N, respectively. The rockets fire until the spacecraft reaches location 449, 541, −354 m. Now what is its speed? There is
negligible mass loss due to the rocket exhaust.
