1. Draw the free-body diagram for a basketball player a) just before leaving the ground on a jump, and b) while in the air.
2. The two forces F1 and F2 a and b act on a 27.0kg object on a frictionless tabletop. If F1 = 10.2N and F2 = 16.0N, find the net force on the object and its acceleration for a and b.

I need help on the second question too.. No Idea how to do it...

I got part a)
Because it is adding vectors I too F1(-10.2) and F2 (-16) therefore ..
F= sqrt( -10.2^2 + -16^2 )
= 18.97 = 19.
F=ma
a= F/m
= 18.97/27.0
= 0.703 m/s^2
tan*=-16/-10.2
*= 57.5 degrees below x-axis
i dont know b though ?
