A swimmer is capable of swimming 0.95 m/s in still water.
(a) If she aims her body directly across a 150 m wide river whose current is 0.55 m/s, how far downstream (from a point opposite her starting point) will she land? (m)
(b) How long will it take her to reach the other side?(s)
The velocity of the swimmer perpendicular to the direction of the stream
vp = 0.95 m/s
width of the river
w = 150 m
velocity of the stream
vs = ...
