1. Two children running along the side of a merry-go-round, push on it to spin it faster, as shown to the right. The first child pushes with E 24.0 N, applied tangent to the merry-go-round at its edge. The second child pushes with Fa-13.O N, also applied tangent to the edge of the merry-go-round. The merry-go-round is free to rotate about its center, has a mass of...
(1 point) Write each of the given numbers in the polar form re',-a <O<n. s= (b) – 31(2 + iv3) p= ,0= (C) (1+i)4 p=
let the polar coordinates of the point (x,y) be (r, theta). Determine the polar coordinates for the points a. (-x,y), b. (-2x,-2y), and c. (3x,-3y). I am not sure why the answer for a. is 180 degress - theta, for b. it's 180 degrees + theta, and for c it's just - theta. If you can break down that part for me that would be great.

PLEASE READ THE NOTE AND FOLLOW FOR THE RIGHT ANSWER !!
"Polar form needs to be in V=[dr/dt](er)+(r)[d theta/dt](e
theta) as shown in the red pen writing. You did not do this for the
question that is why you got is wrong.
Then for cartesian er=cos(theta)i+sin(theta)j and
e(theta)=-sin(theta)i+cos(theta)j. Substitute these two question
for er and e(theta) and multiply them by dr/dt and (r) d theta/dt.
Add all the i and all the j and you will get your final answer...
