This is a classic block on a spring situation. The block is on a horizontal frictionless surface, and the block can undergo simple harmonic motion because it is attached to a horizontal spring. Measuring everything from the end of the spring, the equilibrium position (where the spring is at its natural length) is defined to be x = 0. We'll say that the block is at x = 0 cm when the spring is at its natural length. The block is pulled out to x = +20.0 cm and released from rest at t = 0 s. Part (a) Homework . Answered The block has a mass of 240 grams, and it experiences simple harmonic motion with a period of 4.60 s. Determine the spring constant of the spring.
