An iron ball hangs from a 21.5-m steel cable and is used in the demolition of a building at a location where the acceleration due to gravity is 9.78 m/s2. The ball is swung outward from its equilibrium position for a distance of 4.20 m. Assuming the system behaves as a simple pendulum, find the maximum speed of the ball during its swing

A simple pendulum consists of a ball of mass M hanging from a uniform string of mass m and length L, with m << M. (a) If the period of oscillations for the pendulum is T, derive an expression for the speed of a transverse wave in the string when the pendulum hangs at rest in terms of m, M, T and g (the acceleration due to gravity). Your expression should not include L. (b) If the string is made...

A small pith ball with a charge of -0.600 µC hangs from the end
of a spring as in as in the figure. When another small pith ball of
charge 0.400 µC is held beneath the first pith ball, the spring
stretches by d from its original length and reaches a new
equilibrium position with a separation between the charges of r =
5.00 cm. If the spring constant of the spring is 56.0 N/m, what is
