A 5.0 104 kg space probe is traveling at a speed of 11000 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 4.5 105 N over a distance of 2600 km. What is the final speed of the probe?

    This is the same thing as performing negaive work on the space proble. Multiple retrorocket force x distance to get the kinetic energy change. Get the final speed from the new lower kinetic energy
