Conservation

A simple pendulum oscillates with an amplitude of 30 degrees. If the string length is 1 meter, calculate the speed of the pendulum at its lowest point. The use of energy savings, please explain. CHEEERS. Basically … Conservations of energy: Energy knetic obatins is equal to potential energy reduction. 01. Its height is lowere :1-1 * sin 30 degrees = 0. May 02. The reduction potential energy mgh = m * 9. 8 * 0. 5 0. Three. The energy knetic obatins is: 1/2 * m * v ^ 2 04. M * 9. 8 * 0. 5 = 1/2 * m * v ^ 2 ==> x = (9. 8) ^ 0. 5 =. . . . You can calculate yourself. . . . . This is the first response I made on Yahoo Answers.
