To find: The true direction angle of the canoeist’s path and speed of the canoe.
Answer to Problem 26E
The true direction angle of the canoeist’s path and speed of the canoe are
Explanation of Solution
Given information: River is flowing in east at speed
Calculation:
Let r is the river
Similarly, c is the canoe vector,
Now, the sum of r and c vector will be the canoeist’s path vector p.
Finding the angle of the vector p to get the true directional angle,
The vector p is in the second quadrant, thus, add
Calculating the magnitude of vector p to get how fast the canoe is travelling,
