A 2.30-kg object is moving along the x-axis at 1.90 m/s. As it passes the origin, two forces F⃗ 1 and F⃗ 2 are applied, both in the y-direction (plus or minus). The forces are applied for 2.80 s, after which the object is at x = 5.32 m, y = 11.8 m. . i tried 0i-5.077j that is not correct nor is just -5j express anwser in Fx2,please. If F⃗ 1=11.0j^NF→1=11.0j^N, what's F⃗ 2F→2?
