A canoeist wants to travel straight across a river that is 0.10 km wide. However, there is a strong current moving downstream with a velocity of 3.0km/h. The canoeist can maintain a velocity realitive to the water of 4.0km/h. a) In what diretion should the canoeist head to arrive at a position on the other shore directly opposite to his starting position? b) How Long will the trip take him? AND A jogger runs 15km(N 35 degrees E) and then runs 7.5 km (N 25 degrees W) It takes a total of 2.0 hours to run, a)determine the displacement of the jogger b)calculate the joggers average velocity (I have to break this one into x and y components but I just cant seem to get it right).
