11. what is the net force on the object represented by the free body diagram below: f_air = 40 n f_grav = 25 n
11. what is the net force on the object represented by the free body diagram below: f_air = 40 n f_grav = 25 n
Answer
Explanation:
Step1: Define net - force formula
Net force $F_{net}=F_{up}-F_{down}$
Step2: Identify upward and downward forces
The upward force $F_{air} = 40\ N$ and the downward force $F_{grav}=25\ N$
Step3: Calculate net force
$F_{net}=40 - 25=15\ N$
Answer:
15 N
