the pendulum on a tower that reaches the floor has a period of 20s how tall is the tower?

Answer 1

The period of a pendulum is related to its length by the equation T=2(pi) * square root (length/gravity)

20s= 2*pi*root (length/9.8 m/s²) so rearranging we get approximately 100 meters. Precise answer is 99.24 m
