Fig. 1.1 shows a river in which the velocity of the flowing water is 0.85 m / s parallel to the river banks
A swimmer sets off from one bank. The velocity of the swimmer relative to the water is 1.2 m / s at 45° to the river banks, as shown in Fig. 1.1
In the space below, draw a scale diagram to determine the resultant velocity of the swimmer relative to the river banks. This velocity is the resultant of the two velocities shown on Fig. 1.1
Label this resultant on your diagram
resultant velocity =
