Question

If I have a unit vector of (2.06 j)m/s(I have no i vector because it's 0 on a horizontal impulsion, in accordance with my problem,how do I convert that into polar notation? Will I be doing rcos0, with r being 2.06? . But then again I have no angle, just the angle of before the ball bounces, which was of 70*. Can I simply go with arcTAN of 2,06, but that doesn't seem right to me.

Thank you

Answer 1

(0i+2.06j) is just (2.06,pi/2) in polar coordinates.
