2. A 0.20-km wide river has a uniform flow speed of 3.00 m/s toward the east. A boat with a speed of 8.00 m/s relative to the water leaves the south bank and heads in such a way that it crosses to a point directly north of its departure point. Use these variables: VRE: velocity of river to the earth: Ver; velocity of the boat to the river, vBE : velocity of the boat relative to the earth. a. What is the heading required for the boat to make it straight across? b. What is the resultant velocity with respect to the shore? c. How long does it take the boat to cross the river? d. Draw the vectors representing the relative motions and write down the vector equation that goes with your vector diagram like we did in class.
