A block attached to a horizontal spring is pulled to the right a distance of 19.0 cm from the equilibrium position. The block is released and the block-spring system undergoes SHM at f = 1.28 Hz. Assuming that positive is to the right, determine at 0.300 s after release the block's displacement, velocity, and acceleration. Neglect friction. (Indicate the direction with the sign of your answer.)

A 0.55 kg block rests on a frictionless horizontal countertop, where it is attached to a massless spring whose k-value equals 23.0 N/m. Let x be the displacement, where x = 0 is the equilibrium position and x > 0 when the spring is stretched. The block is pushed, and the spring compressed, until xi = −4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a) What is the block's maximum speed (in m/s) after it...
