Okay. Here are the questions. My comments in red. Any help anyone can give me is appreciated.
Path A is 8.0 km long heading 60 degrees northo of east. Path B is 7 km long in a direction due east. Path C is 4.0 km long heading 315 degrees counterclockwise from east
a. Graphically add the hiker's displacements in the order A, B, C.
b. Graphically add the hiker's displacements in the order C, B, A.
c. What can you conclude about the resulting displacements?
Okay, how the **** to I add the displacements in order? How do I find them at all?
A river flows toward the east. Because of your knowledge of physics, you head your boat 53 degrees west of north and have a velocity of 6.0 m/s due north relative to the shore.
A. What is the velocity of the current?
B What is your speed relative to the water?
How do I find the velocity of the current?
