Two teams of nine members each engage in a tug of war. The first team's members have average masses of 69 kg and exert average forces of 1350 N horizontally. The second team's members have average masses of 74 kg and exert average forces of 1356 N horizontally.

To find which team will win the tug of war, we can compare the total forces exerted by each team. The team with the greater total force will have the advantage and pull the other team towards them.

First, let's calculate the total force exerted by each team. Since both teams have nine members, we can multiply the average force exerted by one member by nine to get the total force for each team.

For the first team:
Total force = Average force * Number of members
Total force = 1350 N * 9 = 12,150 N

For the second team:
Total force = Average force * Number of members
Total force = 1356 N * 9 = 12,204 N

The second team has a greater total force of 12,204 N compared to the first team's total force of 12,150 N.

Therefore, the second team will have the advantage and likely win the tug of war.
