This should be a painfully simple question, and yet, I can't find the answer.
once you have calculated the net acceleration force of an object, how do you figure out how fast it will be going over X seconds?
example (taken from here: http://sciencelearn.org.nz/Contexts/Rockets/Looking-Closer/Calculating-rocket-acceleration)
the shuttle rocket has a NET thrust of 5.25 m/s and that thrust is constant for 124 seconds. how do you calculate the speed? (they get 1380 m/s)
I thought it was 5.25 x (124 ^ 2) = m / s ^ 2 but that answer is way off.
then i thought, maybe it's linear? 5.25 x 124 ? but that answer wasn't correct either..
I looked at other pages giving examples, but they all seem to skip the part where they convert the m/s to the final time frame.
help?
