I dont know the formulas used to find the Fnet of x and y. I keep in getting F_G-F_d=Fn. The problem above is connected to the one below.

10. A projectile is fired up and to the right at an angle e (0 # 0° & 0 # 90°). Identify the directions of the forces listed below that are acting on the projectile
when it is at the peak.
Gravity (FG): 1
Air drag (Fa): -
Normal force (FN): No normal force v
Kinetic friction (F): No kinetic friction v
Static friction (F): No static friction
Tension (F7): No tension ♥
Spring force (Fgp): No spring force
11. Come up with expressions for the net force components for the situation described above (projectile launched up & right). Enter the expression in
terms of the forces by using the symbols listed above. Let down & left be positive.
FG-(-Fa)
Fnetx=
Fc+Fd
Fnet.y = G+F1
