A student bikes to school by traveling first d_N = 1.10 {miles} north, then d_W = 0.500{miles} west, and finally d_S = 0.200 {miles} south. You will now find the same quantity algebraically, without the need to use much geometry. Take the north direction

While a person is walking, his arms swing through approximately a 45° angle in .530s. As a reasonable approximation, we can assume that the arm moves with constant speed during each swing. A typical arm is 70.0 cm long, measured from the shoulder joint.
