Question

An object is hung vertically from a spring with spring constant K=100N/M and stretching the spring by 30 cm. The spring is then stretched an additional 8 cm and release To oscillate. What is the mass of the object hanging from the spring? What is the angular frequency of the objects motion? What is the objects period of oscillation?

Answer #1

An object of mass, m = 0.200kg, is hung from a single spring
with spring constant,
k = 80.0N/m. (Ignore the mass of
the spring.) The object is subject to a resistive force, f,
given by f =-bv
where v = the velocity of the mass in m/s.

A spring of negligible mass and force constant k = 410
N/m is hung vertically, and a 0.210 kg pan is suspended from its
lower end. A butcher drops a 2.4 kgsteak onto the pan from a height
of 0.50 m . The steak makes a totally inelastic collision with the
pan and sets the system into vertical SHM.
a) What is the speed of the pan and steak immediately after the
collision?
b) What is the amplitude of the...

If a spring constant is 40 N/m and an object hanging from it
stretches it 0.50 m, What is the period of the oscillation when the
spring is set into motion?

a. A device consists of an object with a weight of 20.0 N
hanging vertically from a spring with a spring constant of 240 N/m.
There is negligible damping of the oscillating system. Applied to
the system is a harmonic driving force of 13.0 Hz, which causes the
object to oscillate with an amplitude of 3.00 cm. What is the
maximum value of the driving force (in N)? (Enter the
magnitude.)
b.
What If? The device is altered so that...

A 50-cm-long spring is suspended from the ceiling. A 330 gmass
is connected to the end and held at rest with the spring
unstretched. The mass is released and falls, stretching the spring
by 20 cm before coming to rest at its lowest point. It then
continues to oscillate vertically.
a. What is the spring constant?
b. What is the amplitude of the oscillation?
c. What is the frequency of the oscillation?

1. A spring of negligible mass and force constant k = 400N/m is
hung vertically, and a 0.200-kg pan is suspended from its lower
end. A butcher drops a 2.2-kg steak onto the pan from a height of
0.40 m. The steak makes a totally inelastic collision with the pan
and sets the system into vertical SHM.
A) What is the speed of the pan and steak immediately after the
collision?
B) Suppose the mass of the steak is halved,...

A block-spring system consists of a spring with constant
k = 445 N/m attached to a 2.25 kg block on a frictionless
surface. The block is pulled 4.10 cm from equilibrium and released
from rest. For the resulting oscillation, find the amplitude,
angular frequency, frequency, and period. What is the maximum value
of the block's velocity and acceleration?

A 33.0 cm long spring is hung vertically from a ceiling and
stretches to 40.9 cm when a 7.00 kg mass is hung from its free
end.
(a)
Find the spring constant (in N/m).
(b)
Find the length of the spring (in cm) if the 7.00 kg weight is
replaced with a 175 N weight.

A vertical spring stretches 4.4 cm when a 14-g object is hung
from it. The object is replaced with a block of mass 24 g that
oscillates up and down in simple harmonic motion. Calculate the
period of motion.
