Homework Statement


An object of mass 2.5kg is moving in the negative x direction at a velocity of 1.0
m/s. It experiences a force shown of 4N for 3 seconds, what is the final velocity after the object has experienced the impulse.

Homework Equations





The Attempt at a Solution


2.5(v-(-1)=12N
And after that I am not quite sure if that is correct or how to fully solve.

It's correct so far. Now recall from maths that [itex]a-(-b) = a+b[/itex], so [itex]12=2.5\times(v+1)[/itex] and hopefully you should be able to solve for [itex]v[/itex] from there :)
