Unformatted text preview: α + y sin α y' = -x sin α + y cos α a a r a tan a y a x Careful here, positive x is toward the left and positive y downward! Use the fact that the angle the rod makes with the vertical is the same as the angle between a x and a tan and use the information below to write a x and a y as linear combinations of a radial and a tangential (with the appropriate trigonometric functions)....
