Question

in a rectangualar cartesian coordinate system, a certain vector v has r - 10 m/s and θ = -53° . find the x and y components of v?

i know how to solve this but i want to check...i dont have any books

Answer 1

You're going to use standard right-triangle trigonometry to decompose this thing.

x = r cos(theta)

y = r sin(theta)

I get (6.0, -8.0)
