Two small tugboats are pulling a large ship in a harbour. Fig. 1.1 represents the view from above and shows the directions of the forces on the ship.
Each of the tugboats is exerting a force of on the ship.
Determine by a graphical method the resultant of these two forces and state the scale used.
scale ______
resultant = ______
The engines of the ship are not operating and the water in the harbour is stationary. The ship is moving in a straight line in the direction of the total force exerted by the tugboats. It is travelling at a constant speed.
Explain, in terms of the forces acting, why the ship is moving in a straight line at constant speed.
