A700 kg speedboat is pulling a 20 kg inner-tube through the water with a rope that makes a 15 degree angle with horizontal. the thrust provided by the boat's motor is 1,000 n, and the drag forces on the boat and the tube are 200 n and 40 n, respectively. what is the acceleration of the inner-tube? 3)

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

What are the choices?

Pulley, wheel and axle and lever
