Multiple Concept Example 4 and Interactive LearningWare 6.2 review the concepts that are important in this problem. A 37000-kg space probe is traveling at a speed of 9500 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 130000 N over a distance of 3700 km. What is the final speed of the probe?
