Question

In
an experiment a student suspends a 250 g weight using a long spring
mounted vertically to a lab stand, causing the spring to stretch as
much as 18 cm after reaching equilibrium (at rest). She then pulls
the weight at equilibrium position down for 8 cm and let go to set
it into oscillation. Assuming this is an ideal system such that
there is no loss ( leaking) in energy such that the energy such
that the spring will oscillate forever. What is the period of
oscillation ? g= 9.81

Answer #1

When the student suspends the weight then it stretched to 18cm before coming to rest. At the equilibrium position the Force due to gravity is exactly balanced by the restoring force of the spring. Thus we'll have

where k= spring constant.

Then using all given values in SI units in above equation, we'll get

Now We also know that Time Period of Spring Oscillation is given by

then using given mass value and calculated value of "k" we'll get

In an experiment, a student suspends a 650g weight
using a long spring mounted vertically to a lab stand, causing the
spring to stretch as much as 12 cm after reaching equilibrium (at
rest).
She then pulls the weight at equilibrium position down
for 9 cm and let go to set it into oscillation. Assuming this is an
ideal system such that there is no loss (leaking) in energy such
that the spring will oscillate forever?

You hang a 300 g mass on a spring.
a. If the spring initially stretches 6.20 cm when you hang the mass
on it, what is the spring constant?
b. How long will one oscillation take?
The spring is now oriented horizontally and attached to a glider on
a frictionless air track. The glider also has a mass of 300g. You
want to observe the oscillations of this spring-mass system in the
lab with a motion detector. You stretch the...

Finding the Spring Constant
We can describe an oscillating mass in terms of its position,
velocity, and acceleration as a function of time. We can also
describe the system from an energy perspective. In this experiment,
you will measure the position and velocity as a function of time
for an oscillating mass and spring system, and from those data,
plot the kinetic and potential energies of the system.
Energy is present in three forms for the mass and spring system....
