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.)
