thankyou very much! you have been extremely helpful!

so its final velocity is 2m/s?

i not sure how to rearrange this but is it somehting along the lines of sqrt of 1/2ke / m

is that v^2 = 1/2 mass divided by Kintetic energy

kinetic energy? what formula do i use? 1/2 mv^2 is what i have, but i don't have v^2,

into moving the 5kg mass (accelerating from 0?)

am i trying to work out work done? WD = FD, WD = 5N x 2m WD = 10J?

i know how to get kinetic energy but don't know how use that to find its final speed. i have 3 hours to go! ahhhh!

sorry, new to the whole engineering thing, my first week today, could someone give me a lot more help with this sorry.

Homework Statement a body mass of 5kg starts off from rest and is acted upon a force of 5N over a distance of 2m. if there is no frictional forces make use of the principle of the conservation of energy to determinei ts final speed Homework Equations above is all i have. The...
