In the baggage claim area of an American airport, a particular baggage carousel is shaped like a section of a large cone, steadily rotating about its vertical axis. Its surface slopes downward toward the outside, making an angle of Theta= 22.0\ deg with the horizontal. A suitcase having mass m = 30.0 kg is placed on the carousel at a position r = 7.46 m measured horizontally from the axis of rotation. The suitcase goes around once in \Tau = 42.0 s. angular sopeed = 0.150 rad/sec. Linear speed = 1.119m/s (c.) Calculate the force of static friction exerted by the carousel on the suitcase. (Give the magnitude of your answer in Newtons [N]) f =

A wheel of radius 75cm is rotating with a frequency of 3.0Hz about a fixed axis of rotation. What is the speed of a piece of chewing gum stuck to the rim?

This question concerns the linear speed of the Great Pyramid in Egypt relative to the centre of the Earth. The angle between the Earth's axis of rotation and the radial line joining the centre of the Earth to the Great Pyramid is 60.0°. Given that the radius of the Earth is 6.38 x 106 m and that 1 sidereal day = 8.62 × 104 s, what is the linear speed of the Great Pyramid relative to the centre of the Earth due to the Earth's daily rotation? Give your answer in scientific notation, correct to 3 significant figures. Linear speed relative to Earth's centre = X² ms-1.

A centrifuge is a common laboratory instrument that separates components of differing densities in solution. This is accomplished by spinning a sample around in a circle with a large angular speed. Suppose that after a centrifuge in a medical laboratory is turned off, it continues to rotate with a constant angular deceleration for 10.7s before coming to rest.How many revolutions did the centrifuge complete after being turned off?Δθ= (?) rev
