Small rockets are used to make tiny adjustments in the speeds of satellites. one such rocket has a thrust of 35 n. if it is fired to change the velocity of a 72300 kg spacecraft by 60 cm/s, how long should it be fired?

To solve this problem it is necessary to apply the concepts related to the Moment. The momentum represents the product of the mass and velocity of an object, that is

where

m = mass

v = velocity

At the same time using Newtonian relations, we can consider the Moment's equivalence as a function of Force and time as

p = Ft

Where

F = Force

t = time

Matching the two expressions we get that

Re-arrange to find t,

Our values are given as

Replacing we have that the time is

Therefore would be take 1239.4s

heat the gas and measure the pressure
