Discuss and provide example. acceleration is directly proportional to thenet force . This part of the law says that if the force is doubl, then the acceleration is also double. (2F will cause 2a) if it is tripled, then the acceleration will also be tripled, then the acceleration will also be tripled (3F will cause 3a) and so on.​

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.
