What Force is Needed to Reach a New Position in Physics?

[sheers]

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?

yes, you can …

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

what do you get? ​
