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 16.1 s. The acceleration of gravity is 9.8 m/s2 .

A) How tall is the tower?

Answer in units of m

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

Answer in units of s
