Analyze a solar sail that uses the momentum of sunlight for interplanetary travel. A prototype sail of area has been developed You are limited by the design which requires that the supporting frame and the cargo weigh no more than the film itself. Make any necessary assumptions about the parameters of the calculation, and estimate the travel time of this spacecraft from Earth to Mars.

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.
