The thrust of a certain boat’s engine generates a power of 10kW as the boat moves at constant speed 10ms through the water of a lake. The magnitude of the drag force that is exerted on the boat’s hull as it is moving through the water is directly proportional to the boat's speed and is given by the equation F=kv. The increase in power needed for the boat to move through the lake at a constant speed of 12ms is : a. 0W b. 1440 W c. 4400 W 10,000 W e. 4,400 W
