A ball of mass m is connected to one end of a rubber band and swung in a circle. The rubber band has spring constant k, and its unstretched length is r0. If it is swung at an angular velocity ω, to what length will it stretch the rubber band?
Please use energy if you can !! I started to try it using spring potential = rotational kinetic and used I = mr^2 for moment of inertia. but if i plug in like (r+x) for the new radius then if you square there will be cross terms. please help
and if you do it through forces, do you plug in r+x for the spring force or the centripetal force ?

A) Write the Lagrangian for a simple pendulum consisting of a point mass m suspended at the end of a massless string of length l. Derive the equation of motion from the Euler-Lagrange equation, and solve for the motion in the small angle approximation. B) Assume the massless string can stretch with a restoring force F = -k (r-r0), where r0 is the unstretched length. Write the new Lagrangian and find the equations of motion. C) Can you re-write the...

4. A weight of mass 100 gm (0.1 kg) is suspended from a vertical spring causing the spring to stretch so that the distance from the spring's point of suspension to the center of mass of the weight is 20 cm (0.20 m). If the spring and mass are rotated in a horizontal circle, how many RPMS does it take to stretch the spring out to the same length of 20 cm? r 20 cm In other words, how fast...

A ball with a weight of 2 N is attached to the end of a cord of length 2 m. The ball is whirled in a vertical circle counterclockwise. The tension in the cord at the top of the circle is 7 N and at the bottom it is 15 N. (Do not assume that the speed of the ball is the same at these points.) a) Three students discuss the net forces on the ball at the top: Deante:...
