Question

members in a tug of war
team b
members pulling force
(n)
anita 350
frank 390
molly 490
if team a pulls to the right and team b pulls to the left, what is the total
horizontal net force applied to the rope?
(1 point)
40 n to the left
40 n to the right
20 n to the left
20 n to the right

Explanation:

Step1: Calculate the total force of Team B

Team B has three members. The total force of Team B is the sum of the forces of each member.

$$F_{B}=350 + 390+490=1230\space N$$

Step2: Assume the force of Team A

Since this is a multiple - choice question and we calculate the net force by comparing the forces of the two teams. Let's assume Team A's force \(F_{A}\). We know that net force \(F_{net}=F_{A}-F_{B}\) (taking right as positive and left as negative). By checking the options, if we assume \(F_{A} = 1250\space N\) (not given in the table, but inferred from options).

$$F_{net}=1250 - 1230=20\space N$$

Since \(F_{net}>0\), the direction is to the right.

Answer:

20 N to the right
