The Period T of a Conical Pendulum is of 1.1s (the conical pendulum consists of a mass connected to the end of a rope that spins forming a figure of an inverted cone). If the radius of the spin is of 23.7 cm determine the centripetal acceleration of the mass that spins at the end of the rope.

Answer 1

R = 0.237 cm
v = distance /time = circumference C / 1.1 second
C = 2 pi R = 2 * 3.14 * 0.237 = 1.49 meters
so
v = 1.49 / 1.1 = 1.35 meters / second
Ac = v^2/R = 1.35^2 / 0.237 = 7.72 m/s^2
almost 1 g
