Question

forces unit 1 test review you and your brother are playing tug-of-war. you pull with a force of 15 n and your brother pulls with a force of 7 n. what is the net force?

Explanation:

Step1: Identify force directions

Forces in tug - of - war are opposite. Let your force be \( F_1 = 15\space N \) (in one direction) and brother's force \( F_2=7\space N \) (opposite direction).

Step2: Calculate net force

Net force \( F_{net}=F_1 - F_2 \) (since forces are opposite, we subtract magnitudes).
\( F_{net}=15 - 7=8\space N \)

Answer:

The net force is \( 8\space N \) (in the direction you are pulling).
