Question 5

A towing carriage pulls a model ship hull along a straight test tank with a constant horizontal force. The hull is towed 4.0 m to a timing gate and then a further 6.0 m, where the towing stops. During the whole tow, the carriage does 1.2 kJ of work on the hull.

What is the force exerted on the hull by the carriage?
