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

This is a Race Track Interactive Activity. I need help to aswer this question please. I uploaded easy track and medium track. Did you need to keep applying a force to keep the car turning on the track? What direction did you have to apply that force? Be specific and don’t just say “left or right.”
Keplers third law may be obtained from the gravitational force law equated to Newtons 2nd law and replacing the acceleraion by that of a centripetal type. The speed may then replaced by the circumference over the period. We ovatain the ratio of (distance)3 and (Period)2 How does this method outlined above express or represent keplers third law? The escape velocity may be obtained by converting all the gravitational potential energy to kinetic energy. This is a factor of sqrt(2) larger than the orbital speed. Was the approach valid? Justify the obtained relationship.

A spaceship has a rotating compartment which gives its passengers artificial gravity. Suppose this compartment is a cylinder with a radius of 8.3 m. For the artificial gravity to be the same strength as what is experienced on Earth's surface, what would the period of rotation of this compartment need to be, in seconds? Be clear and show all your work. (Uniform Circular Motion)

This can also be expressed in terms of the period (T) of the motion. Period is the time for one revolution (one complete trip of the body around the circle). For one period, the distance the body has traveled is equal to the circumference 2TR of the circle.
