A simple pendulum is constructed by attaching a 0.460 kg ball to a 0.710 m long cord of negligible mass. If air resistance is negligible and the pendulum is swinging such that its maximum angular displacement is 30.0° determine the following.

(a) speed of the ball when it passes through its lowest position

(b) tension in the string when the ball is at its highest position

(c) tension in the string when the ball is at its lowest position

A simple pendulum is constructed from a string of negligible mass. A mass (bob) 0.91kg that is essentially a point mass. The string length is 0.65m. The pendulum is started by being released from rest with an angle (respect to the vertical) of 5.87 degrees. Use g=9.81 m/s^2. a) the maximum amplitude (in degrees) of this motion b)Angular frequency (in rad/s) of this motion c) Period (in s) of this motion.

A ball with a mass of 270 g is tied to a light string that has a length of 2.40 m. The end of the string is tied to a hook, and the ball hangs motionless below the hook. Keeping the string taut, you move the ball back and up until it is a vertical distance of 1.16 m above its equilibrium point. You then release the ball from rest, and it oscillates back and forth, pendulum style. As usual,...
