A 5 kg mass is attached to a massless ideal spring. The spring is set into horizontal SHM with initial displacement x0 = +20 cm and initial velocity v0 = - 5 m/s. The period of the SHM is 4 s. a. Find the spring constant. b. Find the amplitude of the motion. c. Write an equation for this SHM. [Hint: First find ø]
Added by Jes-S V.
Step 1
We know the period of the SHM is 4 seconds. We can use the formula for the period of a spring-mass system: $T = 2\pi\sqrt{\frac{m}{k}}$, where $T$ is the period, $m$ is the mass, and $k$ is the spring constant. Show more…

A mass $m=4.5 \mathrm{kg}$ is attached to a vertical spring with $k=200 \mathrm{N} / \mathrm{m}$ and is set into motion. a. What is the frequency of the oscillation? b. If the amplitude of the oscillation is $3.5 \mathrm{cm}$, what is the maximum value of the velocity? c. How long does it take the mass to move from $y=1.5 \mathrm{cm}$ to $y=2.5 \mathrm{cm} ?$ d. If the mass is oscillating with a maximum speed of $45 \mathrm{m} / \mathrm{s}$, what is the amplitude? e. If the spring constant is increased by a factor of two and the maximum kinetic energy of the mass is the same, by what factor does the amplitude change?
