Homework Statement
A 5.5e4kg space probe is traveling at a speed of 10000 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 5.0e5N over a distance of 2500 km. What is the final speed of the probe?
Homework Equations
velocity=10000
Force=
5e5
displacement=2500
The Attempt at a Solution
I just know the kinematics equations. BUt I have no idea how to start.
