7. A person decides to swim across a river 84 m wide that has a current moving with a velocity of 0.40 m/s [E]. The person swims at 0.70 m/s (N] relative to the water. KI| (a) What is the velocity of the person with respect to Earth? (b) How long will it take to cross' (c) How far downstream will the person land? (d) In what direction should she swim if she lands at a point directly north of her starting position

A swimmer heads 30◦ west of north relative to the water of a 200-m wide river as shown in the figure. Due to theeastward current of the water, when she reaches the opposite bank she finds herself 480 m east of her startingpoint. What is the speed of the river’s current if she can swim with a speed of vS/W = 0.50 m/s in still water?
