vector lab

Apparatus- The apparatus used in this lab is a circular table with degree marks around the edge. There are three pulleys attached to the table. Weight hangers are attached to a central ring with string and run over the pulleys. The central ring is centered around a central pin.

We used trigonometric equations to find the x and y components of the given vectors. y-component=magnitude·sinè x-component=magnitude·cosè We then used vector addition to find the x and y components of the resultant vector. With the x and y components we used the equation magnitude²=(x-component)²+(y-component)² to find the magnitude of the vector and the equation è=arctan(y-component/x-component) to find the angle of the vector.
