To find the net force acting on the ball, we need to consider both the gravitational force and the force of air resistance.
The gravitational force acting on the ball is 10 N down. The air resistance acting against the motion of the ball is 1 N up.
The net force can be calculated using the following formula:
\[
\text{Net Force} = \text{Gravitational Force} - \text{Air Resistance}
\]
Substituting the values:
\[
\text{Net Force} = 10 \, \text{N (down)} - 1 \, \text{N (up)} = 10 \, \text{N} - 1 \, \text{N} = 9 \, \text{N (down)}
\]
Thus, the net force acting on the ball is **9 N down**.
The gravitational force acting on the ball is 10 N down. The air resistance acting against the motion of the ball is 1 N up.
The net force can be calculated using the following formula:
\[
\text{Net Force} = \text{Gravitational Force} - \text{Air Resistance}
\]
Substituting the values:
\[
\text{Net Force} = 10 \, \text{N (down)} - 1 \, \text{N (up)} = 10 \, \text{N} - 1 \, \text{N} = 9 \, \text{N (down)}
\]
Thus, the net force acting on the ball is **9 N down**.
