Question

A simple pendulum (L=1.20m) has a mass of 20.0g at its end. a)calculate the period of oscillation of this simple pendulum. b)suppose the mass is melted and reformed into a uniform rod ( physical pendulum ) so that the period is is the same as the simple pendulum.Determine the length is the physical pendulum.

Explanation / Answer

a)T =2pisqrt(L/g) =2pisqrt(1.2/9.8 ) =2.198sec

b)time period is independent of mass
