Question

A 10-cm-long spring is attached to the ceiling. When a 2.0 kg mass is hung from it, the spring stretches to a length of 15 cm.What is the spring constant k? How long is the spring when a 3.9 kg mass is suspended from it?

Answer #1

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 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 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 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.

A vertical spring is stretched by 15 cm when a mass of 2.0 kg is
attached to it. What additional mass should be added or subtracted
to/from these 2.0 kg to observe 0.5 s period of oscillation?

A scale used to weigh fish consists of a spring hung from a
support. The spring's equilibrium length is 10.0 cm. When a 4.0 kg
fish is suspended from the end of the spring, it stretches to a
length of 13.2 cm.
1. What is the spring constant k for this spring?
Express your answer with the appropriate units.
2. If an 8.0 kg fish is suspended from the spring, what will be
the length of the spring? Express your...

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?

URGENT: A vertical spring is stretched by 15 cm when a mass of
2.0 kg is attached to it. What additional mass should be added or
subtracted to/from these 2.0 kg to observe 0.5 s period of
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...
