a. The projection of a position vector onto any coordinate axis is always the of the of that vector by the with the axis. the vector makes b. As an example of part (a), suppose the Sun is directly overhead and you place one end of a meter-stick on the ground and hold the other end so the meter-stick makes a 60 degree angle with the ground. How long is the shadow cast by the meter-stick?
