Homework Help: physics

A 1.5-kg object moves up the y-axis at a constant speed. When it reaches the origin, the forces F1 = 5.0 N at 37 degrees. above the +xaxis, F2 N in the +X direction, F3 = 3.5 N at 45 degrees below the -X axis, and the F4 = 1.5 N in the - y direction are applied to it. a)Will the object continue moving along the y axis? b) if not, what simutaneous applied force will keep it moving along the y axis at a constant speed?

I described how to do this yesterday. Start by adding the four force vectors. Someone will gladly critique your work.

The mass of the object is not needed to answer the questions.

If you are unfamiliar with how to add vectors, please say so and references can be provided.
