Homework Help: Some More Help Please

    A picture can be seen at the following link:

    The drawing shows a baggage carousel at an airport. Your suitcase has not slid all the way down the slope and is going around at a constant speed on a circle (r = 10.6 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel is 0.760, and the angle in the drawing is 35.6°. How much time is required for your suitcase to go around once (in seconds)?

    I tried at first to use the equation v = 2*pie*r/T and solve for the period T. Since the carousel is at a curve I used the formula tan theta = v^2/rg and solved for v (v= square root of [r*g*tan theta]). I tried then plugging that speed into my first equation and came up with a time of around 7.73seconds. However, the answer is wrong. Any suggestions?
