Question

Select one: a. Ax = -3.1, Ay = +4.6 b. Ax = +3.1, Ay = -4.6 c. Ax = +4.6, Ay = -3.1 d. Ax = -4.6, Ay = +3.1 e. Ax = -4.6, Ay = -3.1 Select one: a. Ax = -3.1, Ay = +4.6 b. Ax = +3.1, Ay = -4.6 c. Ax = +4.6, Ay = -3.1 d. Ax = -4.6, Ay = +3.1 e. Ax = -4.6, Ay = -3.1 a. Ax = -3.1, Ay = +4.6 b. Ax = +3.1, Ay = -4.6 c. Ax = +4.6, Ay = -3.1 d. Ax = -4.6, Ay = +3.1 e. Ax = -4.6, Ay = -3.1 The magnitude of is 5.5. Vector lies in the second quadrant and forms an angle of with the y-axis. The components, Ax and Ay, are closest to: Select one: Ax = -3.1, Ay = +4.6 Ax = +3.1, Ay = -4.6 Ax = +4.6, Ay = -3.1 Ax = -4.6, Ay = +3.1 Ax = -4.6, Ay = -3.1

Explanation / Answer

First, it says that vector A lies in the second quadrant. This means that in a cartessian axis, it will be in minus x and plus y.

Ok, it says too that it will form an angle of 34 degrees with the y axis. So, in order to get the angle you are going to use, you just add 90
