A torsional pendulum consists of a 5 kg. uniform disk with a radius of 0.25 m attached at its center to a rod 1.8 m in length. The torsional spring constant is 0.625 Nm/rad. Disregarding the mass of the rod, what is the undamped natural circular frequency of the torsional pendulum? I. 1.2 rad/s II. 1.0 rad/s Please explain Why III. I=mR², Not 1/2mR²? 1.4 rad/s IV. 2.0 rad/s

You are swinging a sling shot, which is basically a string tied to a rock, vertically as shown. After you get it going fairly fast, you hold your hand stationary so it swings around in a perfect circle. The rock slows down as it gets higher and speeds up as it comes back down. One simple model for how this would work is that the tangential component of the rock's velocity isvt(t)=v0-(v0/4)sin((2pi/T)t) where v0 is the rock's speed at t=0s and T is the time it takes the rock to go all the way around the circle. Call L the length of the string. 1. What is the total acceleration of the rock? 2. What is the angular Acceleration?
