Linear displacement in a circular motion

  1. Sep 30, 2008 #1
    A flea is at point A on a horizontal turntable
    15.7 cm from the center. The turntable is ro-
    tating at 30.5 rev/min in the counterclockwise
    direction. The flea jumps vertically upward to
    a height of 5.18 cm and lands on the turntable
    at point B. Place the coordinate origin at the
    center of the turntable with the positive x axis
    fixed in space and initially passing through A.
    The acceleration of gravity is 9.8 m/s2 .
    Find the linear displacement of the flea.
    Answer in units of m.

    I found the angle through which point A has rotated when the flea lands to be 37.63118767 degrees.

    how would i find the displacement?

    i tried finding the other angles by taking 180-36.63... and / 2 and then using the law of sines but it didn't work.
