Please answer all parts please it is very important for me.
![A child is playing with a ball connected to a string. As the child swings the ball
around, the string is gradually released so that the ball follows a path defined by the
function r = aebe, where a and b are constants, r is the radial coordinate measured
in meters, and is the transverse coordinate measured in radians from the positive
horizontal axis, as shown. The ball is released at point A after making two full
revolutions (i.e., when 0 = 47 radians).
