A hole is drilled through the narrow end of a 0.940-kg baseball bat, and the bat is hung on a nail so that it can swing freely. The bat is 0.820 m long, the hole is drilled 0.0300 m from the end, and the center of mass is located 0.640 m from the end. The period of oscillation is 1.80 s.

(a) What is the bat's rotational inertia about the pivot?

(b) What is the bat's rotational inertia about the center of mass?

(c) If the hole had been drilled 0.250 m from the end, what would the period be?

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...

A uniform plank of mass 2.53 kg and length 21.5 cm is pivoted at one end. A spring of force constant 403 N/m is attached to the center of the plank, as shown in the figure. The height of the pivot has been adjusted so that the plank will be in equilibrium when it is horizontally oriented. Find the period of small oscillation about the equilibrium point. Answer in units of s.
