I was trying this problem and i couldnt come up with a solution, it doesnt seem to hard but I cant think of what to do.

There is a point on a wheel that is rotating at a constant speed. The bottom of the wheel is 1 meters above the ground. At a point Q the point on the wheel is 16 meters above the ground. After 4 seconds its reaches the top of the wheel. After another 8 seconds it reaches a point P. If the wheel has a diameter of 16 meters how do we find out how high the point is at point P.

Thanks!

    If you can use coordinates, they might help greatly. Center the rotating circle on the vertical axis; trigonometry might be helpful.2012-04-15
