Rocket engines on it are fired

Assignment Help Physics
Reference no: EM131321904

As a spacecraft approaches a planet, the rocket engines on it are fired (turned on) to slow it down so it will go into orbit around the planet. The spacecraft's mass is 2,525 kg and the thrust (force) of the rocket engines is 325 N. If its speed must be decreased by 1,259 m/s, how long (in minutes) must the engines be fired? (Ignore the change in the mass as the fuel is burned.)
