Asked by Alex
A river flows at a speed of 4.60 m/s. A boat, capable of moving with a speed of 5.80 m/s in still water is rowed across the river at an angle of 53.0° to the river flow. Calculate the resultant velocity with which the boat moves and the angle that its resultant motion makes to the river flow.

Vr = 4.6 + 5.8[53o]=
4.6 + 5.8*Cos53 + 5.8*sin53 =
4.6 + 3.49 + 4.63i = 8.09 + 4.63i =
9.32m/s[29.8o].
4.6 + 5.8*Cos53 + 5.8*sin53 =
4.6 + 3.49 + 4.63i = 8.09 + 4.63i =
9.32m/s[29.8o].
