: A Simple Pendulum Of Length L Has A Maximum Angular Displacement 0 Max At One Point In Its Motion Its Kinetic Energy 1 (185.05 KiB) Viewed 200 times

: A Simple Pendulum Of Length L Has A Maximum Angular Displacement 0 Max At One Point In Its Motion Its Kinetic Energy 2 (119.88 KiB) Viewed 200 times

A simple pendulum of length L, has a maximum angular displacement 0_max. At one point in its motion, its kinetic energy is K = 3 J and its potential energy is U = 4.2 J. When the pendulum's angular velocity is half its maximum value (0' = 0'_max/2), then its kinetic energy is:
A block-spring system oscillates on a frictionless horizontal surface. The time needed for the block to complete one cycle is 0.1 sec. Determine the time needed for the block to travel from -A/2 to A/2, where A is the amplitude of motion.
