One-dimensional collisons

  1. Oct 24, 2013 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations



    3. 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 :)
