Please Explain this?

Re: Please Explain this?!?!?!

A little more information regarding the problem would be helpful. However, how can one divide Newtons by time and wind up with Newtons?

Have you covered momentum yet? I don't remember how to calculate force of thrust without using momentum, so I hope this is helpful to you.

The equation for Force of Thrust I know, is
F(thrust) = ((m * V)2 - (m * V)1) / (t2 - t1)

This can also be written as
F(thrust) = Δp / Δt
Force of thrust = change in momentum / change in time

Which would give you
N = N*s/s
meaning your seconds would cancel to give the correct units.

the doth prevous questins are pretty good. But i dont understand why did u posted a quastion that is already answered.. If you dont understand it just read the 3-4 prevous pages of your book!
