Answer to Question #175341 in Physics for Mae Joy Candungo

Question

A vector has a magnitude of 9.1 and is in quadrant 1 with an angle of 30.3° with respect to the +y-axis. What is the ×-component of the vector?

Answer 1

We can find the $x$-component of the vector as follows:

$$sin\theta=\dfrac{A_x}{A},$$ $$A_x=Asin\theta=9.1\cdot sin30.3^{\circ}=4.6.$$
