Problem 7P

Two canoeists start paddling at the same time and head toward a small island in a lake, as shown in Figure 4-12. Canoeist 1 paddles with a speed of 1.35 m/s at an angle of 45° north of east. Canoeist 2 starts on the opposite shore of the lake, a distance of 1.5 km due east of canoeist 1. (a) in what direction relative to north must canoeist 2 paddle to reach the island? (b) What speed must canoeist 2 have if the two canoes are to arrive at the island at the same time?

Solution 7P

Step 1 of 6

Here our objective is to to determine the direction relative to north the canoeist 2 must paddle so as to reach the island and then we need to calculate the speed of the canoeist 2 , if both the canoes reach the island at the same time.
