Achild on a playground swings through a total of 32°. if the displacement is equal on each side of the equilibrium position, what is the amplitude of this vibration?

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .
