Small rockets are used to make small adjust- ments in the speed of satellites. One such rocket has a thrust of 42 N. If it is fired to change the velocity of a(n) 83000 kg space craft by 71 cm/s, how long should it be fired? Answer in units of s

OpenStudy (nurali):

F = 42 N Mass = 83000 kg v = 0.71 m/s t = 83000 kg * 0.71 m/s * 1/ 42N t = 1403 sec
