The net force on the ball at its maximum height is determined as zero.
The net force on the ball at its maximum height is calculated as follows;
F(net) = F - Fg
where;
F is the applied force
Fg is force of gravity
at maximum height, velocity = 0, and acceleration of the ball will be zero.
0 = 5 - Fg
Fg = 5N
Thus, the net force on the ball at its maximum height is determined as zero.
