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?

A charge Q is fixed at the origin. At t = 0 a particle of mass
2.0 g and charge -3.0μC is located on the x-axis at x = 10 cm,
