The position of the block as a function of time is: The problem stated: x(t) = A cos(ωt +

"A 2.0 kg block is attached to a horizontal, massless spring with a force constant of 100 N/m. The block is displaced 0.20 m to the right of its equilibrium position and then released from rest. Assuming that the block undergoes simple harmonic motion, determine the block's position as a function of time." The position of the block as a function of time is: "A 2

A recurring issue is failing to include correct units on final numerical answers, which often results in a 1-point deduction even if the calculation is correct.
