What is the final speed of the probe?

A 5.5 x 10^4 kg space probe is traveling at a speed of 15000 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 3.5 x 10^5 N over a distance of 2500 km. What is the final speed of the probe?|||F d = 1/2m ( V1^2 - V2^2)





solve for V2
