Question

The x vector component of a displacement vector r has a magnitude of 150.0 m and points along the negative x axis.
The y vector component has a magnitude of 180.0 m and points along the negative y axis

A) Find the magnitude of r.
B) Specify the direction with respect to the negative x axis in degrees. (Use unit of "deg".)

The x vector component of a displacement vector r has a magnitude of 150.0 m and points along the negative x axis. The y vector component has a magnitude of 180.0 m and points along the negative y axis Find the magnitude of r. Specify the direction with respect to the negative x axis in degrees. (Use unit of "deg".)

Explanation / Answer

A. magnitude = sqrt(x^2 + y^2) =234.31 m

B. theta =tan-1(180 /150) = 50.19 degrees
