An object is attached to an ideal spring of spring constant $2.5 \mathrm{N} / \mathrm{m}$. The spring is initially in its relaxed position. The object is then released and oscillates about its equilibrium position. The motion is described by $$ y=(4.0 \mathrm{cm}) \sin [(0.70 \mathrm{rad} / \mathrm{s}) t] $$ What is the maximum kinetic energy?

Step 1
We know the displacement equation is given by: $$ y = A \sin(\omega t) $$ where $A$ is the amplitude, $\omega$ is the angular frequency, and $t$ is the time. Show more…

An object is attached to an ideal spring of spring constant 3.08 N/m. The spring is initially in its relaxed position. The object is then released and oscillates about its equilibrium position. The motion is described by y = (3.97 cm) sin[(0.700 rad/s)t]. What is the maximum kinetic energy?

A 0.50 kg object is attached to an ideal spring of spring constant (force constant) 20 N/m along a horizontal, frictionless surface. The object oscillates in simple harmonic motion and has a speed of 1.5 m/s at the equilibrium position. At what distance from the equilibrium position are the kinetic energy and potential energy of the system the same?

A $4.0 \mathrm{N}$ object is attached to the bottom of an ideal spring of spring constant $250 \mathrm{N} / \mathrm{m}$. The spring is initially in its relaxed position. Write an equation to describe the motion of the object if it is released at $t=0 .[$Hint: Let $y=0$ at the equilibrium point and take $+y=$ up. $]$
