1. The problem statement, all variables and given/known data Sophie walks 800 M [N], then 500 M [W] and finally 400 M [SE] in 25 minutes. What is her displacement and average velocity? (Using scale diagram) 2. Relevant equations a2 + b2 = c2 3. The attempt at a solution I tried calculating by creating separate triangles, but was not certain what to do with the 400 M [SE] as I was not given an angle. This was my attempt, assuming that both south and east are 400 M Y = 800 north - 400 south = 400 M north X= -500 or 500 west + 400 east = -100 or 100 west Using Pythagorean theorem, I calculated for size Z and got 412.3 M Then moving forward from that to calculate the direction, I said tan-1 (100/400) equals 14 degrees. My final answer was 412.3 M [W 14 degrees N] Now I also do not have an answer key and this is an assignment that I can't figure out. Any help would be appreciated, thank you!
