a boat heads due east across a stream with a velocity of 20m/s. the stream is flowing from north to south at a rate of 5.0m/s.
a)What is the resultant velocity?
b) if the stream is 100 m wide, how much time does it take the boat to reach the other side?
c) How far downstream is the boat when it reaches the other side?
The Attempt at a Solution
for the resultant, i just took pythagorean theorem to find out an answer of 20.6m/s. that angle I got by using tan inverse. which is 14.0 degrees
To get the time do i just take the 100m and divide it by the resultant velocity?
How do i find how far downstream the boat is when it reaches the other side?
