A flea is at point A on a horizontal turntable, 9.5 cm from the center. The turntable is rotating at 33.3 rev/min in the clockwise direction. The flea jumps straight up to a height of 4.99 cm. At takeoff, it gives itself no horizontal velocity relative to the turntable. The flea lands on the turntable at point B . Choose the origin of coordinates to be at the center of the turntable and the positive x axis passing through at the moment of takeoff. Then the original position of the flea is 9.5i cm. (Give the position relative to the turntable.) (a) Find the position of point A when the flea when the flea lands. (b) Find the position of point B when the flea lands

    I think you have to convert rev/min into radians per second

    I also remember a question where the velocity of a flea's jump is given so you must calculate the time and then the angle that the record goes through

    I calculated the time and the velocity of the flea's jump, not sure how to calculate the angle though

    |dw:1349561329581:dw| where t is the time (in seconds) that the flea was in the air
