A simple pendulum consists of a 1.00-kg bob on a string 1.00 m long. During a time interval of 25.0 s , the maximum angle this pendulum makes with the vertical is found to decrease from 6.00 ∘ to 5.50 ∘.

Part A

Determine the numerical value of the time constant τ.

Express your answer with the appropriate units.

τ =

Part B

Determine the numerical value of the damping coefficient b.

b =
