A small polished glass ball P of mass mrall = 20 g moves on the inside smooth surface of a spherical bowl of internal radius r = 25 cm. The object rotates with constant angular speed w, in a horizontal circle which is at a depth of r/2 below the centre of the bowl. It is required to determine: a) The magnitude of Normal reaction acting on object P; b) The linear speed and the time it takes the small ball to do a full rotation of its circular path.

A bolt is threaded onto one end of a thin horizontal rod, and the rod is then rotated horizontally about its other end. An engineer monitors the motion by flashing a strobe lamp onto the rod and bolt, adjusting the strobe rate until the bolt appears to be in the same eight places during each full rotation of the rodThe strobe rate is 2000 flashes per second; the bolt has mass 30 g and is at radius 3.5 cm.What is the magnitude of the force on the bolt from the rod?

On a 12.0-cm-diameter audio compact disc (CD), digitalbits of information are encoded sequentially along anoutward spiraling path. The spiral starts at radius R1=2.5cmand winds its way out to radius R2=5.8cmTo read the digital information, a CD player rotates theCD so that the player’s readout laser scans along thespiral’s sequence of bits at a constant linear speed of 1.25 m/sThus the player must accurately adjust the rotational frequency f of the CD as the laser moves outward.Determine the values for f (in units of rpm) when thelaser is located at R1 and when it is at R2
