7. small rockets are used to make tiny adjustments in the speeds of satellites. one such rocket has a
thrust of 31 n. if it is fired to change the velocity of a 65000 kg spacecraft by 106 cm/s, how long should
it be fired?

222.3 s

Explanation:

From Newton’s law, F=ma hence

Time,

Where is change in velocity

The change in velocity is equivalent to 0.106 m/s

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
