Answer to Question #19726 in Mechanics | Relativity for Waseem
Question # 4
If an object on a horizontal, frictionless surface is attached to a spring, displaced, and then
released, it will oscillate. If it is displaced 0.120 m from its equilibrium position and released
with zero initial speed, then after 0.800 s its displacement is found to be 0.120 m on the opposite
side, and it has passed the equilibrium position once during this interval.
Find (a) the amplitude; (b) the period; (c) the frequency.
