The diagram below represents the forces acting upon a leftward-moving object. Each arrow represents a force; the length of the arrow represents the strength of
the force.
Is this a speeding up, slowing down, or constant speed motion?

Good moring let me you on this question the answer the electric force  have a good day ; )

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.
