Question

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.

Answer #1

If due to weight 'W' the spring ( spring constant 'k') is extented by 'x' then

W=kx

A 8.0-cm-long spring is attached to the ceiling. When a 2.5 kg
mass is hung from it, the spring stretches to a length of 17 cm
.
1. What is the spring constant k?
2. How long is the spring when a 3.0 kg mass is suspended from
it?

A 12 cm long spring is attached to the ceiling. When a 2.4 kg
mass is hung from it, the spring stretches to a length of 17
cm.
(a) What is the spring constant k?
N/m
(b) How long is the spring when a 3.2 kg mass is suspended from
it?
cm

A spring is hung from the ceiling, and has a rest length of 43.0
cm. A block (mass = 0.374 kg) is attached to the spring. When we
slowly let the mass down (being careful to not let it start
oscillating), the spring stretches to a length of 58.4 cm. We then
pull the mass down 3.0 cm below this position and let it go to
begin oscillating. Assume the mass of the spring is negligible.
a) What is the...

A spring is hanging vertically from a shelf. When a weight of
mass 0.16 kg is hung from the spring, the spring stretches a
distance 25 cm. That weight is then removed and a new weight of
mass 0.30 kg is hung from the spring. This second weight is then
lifted a distance of 1.8 cm and released. The weight oscillates up
and down. What is the period of oscillation (in units of
seconds)?

A spring is hung from the ceiling. A 0.422 -kg block is then
attached to the free end of the spring. When released from rest,
the block drops 0.130 m before momentarily coming to rest, after
which it moves back upward. (a) What is the spring constant of the
spring? (b) Find the angular frequency of the block's
vibrations.

An ideal spring hangs from the ceiling. A 2.15 kg mass is hung
from the spring, stretching the spring a distance d = 0.0905 m from
its original length when it reaches equilibrium. The mass is then
lifted up a distance L = 0.0225 m from the equilibrium position and
released. What is the kinetic energy of the mass at the instant it
passes back through the equilibrium position?

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.

A spring 1.7 m long with force constant 525 N/m is hung from the
ceiling of an elevator, and a block of mass 15 kg is attached to
the bottom of the spring.
(a) By how much is the spring stretched when the block is slowly
lowered to its equilibrium point?
(b) Referring to your answer in Part (a), is the block below or
above its equilibrium position?
(c) If the elevator subsequently accelerates upward at 2.00
m/s2, what is...

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?

A 2 meter long mass less spring is hanging from the ceiling. You
hang a 1 kg weight to the bottom of the spring. After the weight is
attached the spring stretches 5 cm down. You take off the weight
and removed the spring from the ceiling and place it on the floor
so it is horizontal.
1. There is no friction on the floor. Calculate the maximum
compression that the spring reaches at its relaxed position if you
fire...
