W- A river has a current flowing with a velocity of 2.0 meters per second due east. A boat is 75 meters from the north riverbank. It travels at 3.0 meters per second relative to the river and is headed due north. In the diagram below, the vector starting at point Prepresents the velocity of the boat relative to the river water. 2445 N 75 m 3.0 m/s North riverbank 2.0 Dock South riverbank 10Calculate or find graphically the magnitude of the resultant velocity of the boat. [Show all work, including the equation and substitution with units or construct the resultant velocity vector for the graph, using a scale of 1.0 centimeter = 0.50 meter per second. The value of the magnitude must be written below] 1 Calculate the time required for the boat to cross the river. [Show all work, including the equation and substitution with units.]
