physics
A person jumps from the roof of a house 3.6 -m high. When he strikes the ground below, he bends his knees so that his torso decelerates over an approximate distance of 0.70 {\rm m}. If the mass of his torso (excluding legs) is 46 kg. Find the average force exerted on his torso...

physics/ math
I figured this out. For those that may need help with a question like this. Because of the North direction being the displacement vector... there was a 90 degree angle. So... (1.1)(cos90) = 0 (1.1)(sin90) = 1.1 Answer: (0, 1.1)

physics/ math
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 as the positive y dire...
