A block of 0.42 kg attached to a horizontal spring whose spring constant is 130.00 N/m has a simple harmonic motion (SHM) with an amplitude of 0.11 m. The figure above shows one complete cycle of the SHM, and the vertical green dashed line indicates the equilibrium position of the block.
(d) Calculate the block 's velocity at 0.045 s. The velocity can be positive, zero or negative.
Notice that the unit of angular frequency ω is rad/s, the unit of time is second, therefore the unit of (ω×t) is radian.
(f) Calculate the block 's position at 0.223 s. The position can be positive, zero or negative.
(g) Calculate the block 's velocity at 0.223 s. The velocity can be positive, zero or negative.
(h) Calculate the block 's acceleration at 0.223 s. The acceleratio can be positive, zero or negative.
