Problem
A small stone is tied to one end of a string 0.60m long and whirled in a horizontal circle making 4 revolutions every second.
(a) Calculate the linear speed of the stone.
(b) Determine the centripetal acceleration of the stone.
(c) Express the acceleration obtained in part (b) as a multiple of g(g=9.8m s−2)."
