An unusual object of mass M is hung from its center of mass by a light wire, of length Lo, to form a physical pendulum with period of oscillation T. The length of the wire is then shortened to half of its original length. Solve for the period of oscillation in the shortened scenario, if the original length and period were Lo = 0.77m and T = 2.3s, respectively. (Reminder: You are expected to solve this algebraically before subbing in numerical values. Hint: The moment of inertia is NOT m Lo^2 .)

A small mass is hung at the end of a light string of length 1.5 m and allowed to swing over a small amplitude as a simple pendulum. It is observed that the amplitude of swing is reduced to half its initial value in 30 complete swings. It may be assumed that the reduction of amplitude is due entirely to resistance of the air and this in turn may be assumed to be proportional to the velocity of the mass....

pendulum of mass m= 0.8 kg and length l=1 m is hanging from the ceiling. The massless string of the pendulum is attached at point P. The bob of the pendulum is a uniform shell (very thin hollow sphere) of radius r=0.4 m, and the length l of the pendulum is measured from the center of the bob. A spring with spring constant k= 7 N/m is attached to the bob (center). The spring is relaxed when the bob is...

Consider a ‘physical pendulum’ made of a meter stick (length L = 1 m, mass 0.2 kg) with a hole drilled through it at the 5 cm mark. The stick is free to rotate (in a vertical plane) around a nail that goes through the hole and into a wall. Assume no friction between the nail and the hole. The stick’s moment of inertia about the nail is I=0.1 kgm2. (Use g=10 m/s2) If the pendulum is released from rest...
