Question

calculate the net force shown in the diagram? 200n f_air 600n f_gravity 800 n 400 n 600 n

Explanation:

Step1: Define directions. Upward positive, downward negative.

$F_{\text{air}} = +200\,\text{N}, F_{\text{gravity}} = -600\,\text{N}$

Step2: Calculate net force by summing.

$F_{\text{net}} = 200\,\text{N} + (-600\,\text{N}) = -400\,\text{N}$ (magnitude 400N)

Answer:

400 N
