the speed of river relative to ground , vrg = 1 m/s * ( cos(45) i + sin(45) j)
vrg = 0.71 i m/s + 0.71 j m/s
the speed of canoe relative to ground , vcg = - 0.2 m/s i
the velocity of canoe relative to river , v = vcg - vrg
v = (-0.2 i) - (0.71 i + 0.71 j) m/s
v = ( - 0.91 i m/s - 0.71 j m/s)
the magnitude of velocity of canoe relative to river , |v| = sqrt(0.91^2 + 0.71^2) = 1.15 m/s
the direction of velocity of canoe relative to river , theta = arctan(0.71/0.91) south of West
theta = 37.96 degree South of West

3) 35 pts. Water in a river flows with a component downstream (x-direction) of 6 m/s and a component across the stream (y -direction) of 4 m/s. A boat is attempting to cross the river. The velocity of the boat relative to the water is 20 m/s at an angle of 70 degrees with respect to the x-axis. Determine the velocity of the boat relative to the shore.
