As a space craft approaches a planet, the rocket engines on it are fired to slow it down so it will go into orbit around the planet. The spacecraft's mass is 251 kg and the thrust (force) of the rocket engines is 54 N. If the speed of the spacecraft must be decreased by 135 m/s, how long must the engines be fired. (Ignore the change in mass due to the rocket engines firing).
