Question

A man enters a tall tower, needing to know its height. He notes that a long pendulum extends from the ceiling almost to the floor and that its period is 11.5 s.
(a) How tall is the tower?
_________  m

(b) If this pendulum is taken to the Moon, where the free-fall acceleration is 1.67 m/s2, what is the period there?______S

Henry · Accepted Answer

a. h = g*T^2/4pi^2. h = 9.8*(11.5)^2/39.4 = 32.9 m. b. T^2 = 4pi^2*(L/g). T^2 = 39.4*(32.9/1.67) = 776.2 T = 27.9 s. = Period

Bot · Answer

Pi (π) is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. It is approximately equal to 3.14159, but is an irrational number with decimal digits that go on infinitely without repeating in a pattern.
