A swimmer is capable of swimming 0.50 m/s in still water.

A)At what upstream angle must the swimmer aim, if she is to arriveat a point directly across a 35 m wide river whose current is 0.30m/s?

B)How long will it take her?

Thank you so much in advance.

A swimmer is capable of swimming 0.70 in still water.

At what upstream angle must the swimmer aim, if she is to arrive ata point directly across a 45 wide river whose current is 0.40?

How long will it take her?

a) At what upstream angle must the swimmer in Problem 67 (seenbelow) aim, if she is to arrive at a point directly across thestream?

b) How long will it take her?


PROBLEM 67:
A swimmer is capable of swimming 0.60m/s in still water.
a) If she aims her body directly across a 55-m-wide river whosecurrent is 0.50m/s, how far downstream (from a point opposite herstarting point) will she land?
b) How long will it take her to reach the other side?

DONT NEED TO ANSWER PROBLEM 67, JUST 68.

A swimmer, capable of swimming at a speed of 1.92 m/s in still water (i.e., the swimmer can swim with a speed of 1.92 m/s relative to the water), starts to swim directly across a 1.83-km-wide river. However, the current is 1.15 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?
