Question 38069: 1.A pendulum swings through an arc of 660 centimeters. On each successive swing, the length of the arc is 6/7 of the previous length. Find th total distance the pendulum travels before it comes to rest. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! This is an infinite series with a1 = 660 and r = 6/7. The formula for the sum of such a series is
S(infinity) = a1 / (1 - r) = 660 / (1 - 6/7) = 660 / (1/7) = 4620 cm
