Two tugboats are towing a ship. Each exerts a horizontal force of 5 tons and the angle between their towropes is 90°. What net force is exerted on the ship?

90

10

To find the net force exerted on the ship, we first need to find the horizontal components of the forces exerted by the two tugboats.

The horizontal component of a force can be found using the formula:
Horizontal Component = Force * cos(angle)

In this case, both tugboats exert a force of 5 tons. Since the angle between their towropes is 90°, the formula becomes:
Horizontal Component = 5 tons * cos(90°)

The cosine of 90° is 0, so the horizontal component of each force is 0 tons.

Since the horizontal components cancel each other out (0 + 0 = 0), the net force exerted on the ship is 0 tons.
