Question

1. what is the net force on the object represented by the free body diagram below: f_air = 40 n f_grav = 25 n

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
