According to the net force, the ball will go forward with 600 N.
We need to know about force resultant to solve this problem. The force resultant is the total net force applied to the object according to the direction. It can be written as
R = F1 + F2 + ... + Fn
where R is force resultant (net force)
According to the direction which forward is positive and backward is negative, the force is
F1 = 200 N
F2 = 200 N
F3 = 200 N
F4 = -200 N
F5 = -200 N
F6 = 400 N
F7 = 400 N
F8 = -400 N
Hence, the net force is
R = F1 + F2 + F3 + F4 + F5 + F6 + F7 + F8
R = 200 + 200 + 200 - 200 - 200 + 400 + 400 - 400
R = 600 N
