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...

A string is attached to a ball and the ball is being swung in a horizontal circle. The string exerts a force on the ball. In what direction is the force always directed? While the string is attached to the ball and the ball moves in a horizontal circle at a constant speed, does the force change both the direction and speed of the ball? Does the force change both direction of travel and speed of the ball? Explain. An...
