11. A small button placed on a horizontal, rotating platform with diameter 0.320 m will revolve with the platform when it is brought up to a rotational speed of 37.0 rev/min, provided the button is no more than 0.140 m from the axis. to in What is the coefficient of static friction between the button and the platform? lda How far from the axis can the button be placed, without slipping, if the platform rotates at 60.0 rev/min? 13. A 5.0-m-diameter merry-go-round is turning with a 4.2 s period. What is the speed of a child on the rim? 14. The blade on a table saw spins at 3800 rpm. Its diameter is 25.0 cm. What is the speed of a tooth on the edge of the blade in m/s? What is the speed of a tooth on the edge of the blade in mph? 15. An old-fashioned LP record rotates at 33 rpm. What is its frequency in rev/s? What is its period, in seconds? Imoshod e i so s W lda 16. A typical hard disk in a computer spins at 10000 rpm. What is the frequency, in rev/s? What is the period, in seconds? 17. A CD-ROM drive in a computer spins the 12-cm-diameter disks at 7300 rpm. What is a disk's period in s? What is a disk's frequency in rev/s? 18. The horse on a carousel is 4.1 m from the central axis. If the carousel rotates at 0.14 rev/s, how long does it take the horse to go around twice? How fast is a child on the horse going (in m/s)? 19. The radius of the earth's very nearly circular orbit around the sun is 1.50x10"m. Find the magnitude of the earth's velocity as it travels around the sun. Assume a year of 365 days. Find the magnitude of the earth's centripetal acceleration as it travels around the sun. Assume a year of 365 days. Jarger than they appear, and despite their apparently lazy motion, the speed of wind speed. A turbine has blades 54 m long

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal for…
