How far are you from the Starting Point?
A city has streets laid out in a square grid, with each block 135 m long. If you drive north for three blocks, then west for two blocks, how far are you from your starting point? Now use the Pythagorean theorem. A2 + B2 = C2. (405)2 + (270)2 = C2 √236,925 = √C2…

Magnitude of Displacement
A garden has a circular path of radius 50 m. John starts at the easternmost point on this path, then walks counterclockwise around the path until he is at its southernmost point. What is the magnitude of John’s displacement? 50² + 50² = x² 2500 + 2500 = x² x = 70.74 What is…
