Hi Guys!

Question

Need help with this physics problem, I have no idea how to set it up or how to visualize it but would appreciate any help.

Instructions for finding a buried treasure include the following: Go 80 paces at 235°, turn to 130° and walk 115 paces, then travel 100 paces at 157°. Determine the resultant displacement from the starting point.

Thanks in advance!

Answer 1

You can do it on a piece of polar graph paper.

Or, you can break up each vector into N,E components, then add.

N component=Magnitude*cosTheta
E component=Magnitude*sinTheta.

It works every time.
