A river is moving east at vWE = 3.97 m/s. A boat starts from the dock heading θ = 33.9 degrees north of west at vBW = 9.12 m/s, relative to the water. The river is w = 1380 m wide.
Part (a) Write an expression for the speed of the boat with respect to Earth (vBE) in terms of variables from the problem statement.
B) Write an expression for the time t it takes the boat to cross the river in terms of variables from the problem statement.
Part (c) What is the speed of the boat, in m/s, with respect to Earth?
Part (d) How long, in seconds, does it take the boat to cross the river?
