A 2.50 kg object is moving along the x-axis, in the positive direction, at1 .60 m/s. As it passes through the origin, two forces F1 and F2are applied, both forces only have components in the y-direction (Note: The y-components of either force could be positive or negative). The forces are applied for 3.00 s, after which the object is atx=4.80 m,y=10.8 m.If~F1=15.0ˆjN, what is~F2?
