Question

Find the direction of the sum ofthese two vectors:BW TOT60.0 °85.0 mA

Answer 1

We are given two vectors and we are asked to determine the direction of their sum. To do that we will rewrite them on coordinates form. For vector A, since it is a horizontal vector it only has an x-coordinate equivalent to its magnitude, like this:

`A=(85,0)`

For vector B we will use the following formula:

`B=(\lvert B\rvert\cos \theta,\lvert B\rvert\sin \theta)`

Replacing the values:

`B=(101\cos 60,101\sin 60)`

Solving the operations
