At an airport a circular luggage belt is shaped like a cone with the top cut off (let theta=15.0 deg.). The radius at the top is 0.500 m and at the very bottom of the cone is 2.50 m. it takes 30.0 seconds to make one rotation.
a. What would the speed of your suitcase be if it was at the top, bottom or right in the middle?
b. Draw a fbd of the forces acting on it. (with friction)
c. Assuming your 30.0 kg suitcase is at rest in the middle of the ramp, what must the net force in the radial direction be?
d. If your suit case is to stay at this position what is the coefficient of static friction?
