A 5.50 104 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 4.00 105 N over a distance of 2600 km. What is the final speed of the probe?

The decrease in momentum, M*(V1 - V2)

is equal to the retrorocket thrust force times the time.

Solve for V2.
