Homework Help: Force and Motion question

  1. Apr 12, 2010 #1
    A 2.50kg object is moving along the x-axis at 160m/s. as it passes the origin, two forces F1 and F2 are applied, both in the y direction f1=15N in the j direction. The forces are applied for 3.00s after which the object is at the point x=4.80m y=10.8m. Find f2.

    can anyone figure out how to do this?

    Hi sheers! Welcome to PF! :smile:
    yes, you can :wink:

    use good ol' Newton's second law (F = ma), and the standard constant acceleration equations …

    what do you get? :smile:
