Question

Position vector r⃗ has magnitude of 19.4m and direction angle 235 degrees

What are the x and y components? (x,y)
Find the components of the vector −2r⃗ and the magnitude of the vector?
Find components of vector -2r
x = 19.4 cos 235°
y = 19.4 sin 235°

multiply by -2 to get the x,y of -2r.
multiply 19.4 by 2 to get the magnitude
