Question

A sphere is attached to a vertical spring of constant k = 11,990 N/m. As the sphere is allowed to hang from the spring, it also is partially submerged in water, where 60% of its volume is underwater. When the sphere is in equilibrium, it has displaced the spring by 10.0 cm from its relaxed length. The density of the sphere is 4250 kg/m3. (a) Has the spring stretched or compressed? Explain. (b) What is the radius of the sphere?

Answer #1

A spring with spring constant 32 N/m is attached to the ceiling,
and a 4.7-cm-diameter, 1.2 kg metal cylinder is attached to its
lower end. The cylinder is held so that the spring is neither
stretched nor compressed, then a tank of water is placed underneath
with the surface of the water just touching the bottom of the
cylinder. When released, the cylinder will oscillate a few times
but, damped by the water, quickly reach an equilibrium
position.

0.2 kg mass gets pushed down against a vertical spring with
spring constant k=1000N/m. when the spring is compressed by 10 cm
the object is let go. what is the speed of the object the second
its let go from the spring. (i.e. the spring is at its equilibrium
length) answer in m/s

A 50-gram mass is attached to a vertical spring; the spring
stretches 8.0 cm. Determine the stiffness of the spring. If it is
now stretched an additional 2.0 cm, determine its period and
frequency of oscillation.

A block of mass m = 0.53 kg attached to a spring with force
constant 119 N/m is free to move on a frictionless, horizontal
surface as in the figure below. The block is released from rest
after the spring is stretched a distance A = 0.13 m. (Indicate the
direction with the sign of your answer. Assume that the positive
direction is to the right.)

A spring with a force constant k = 200 N/m is attached
to the bottom of a large beaker which is then filled with water
(figure (a)). A block of pine wood with a mass of 4.10 kg and a
density of 630 kg/m3 is connected to the spring and the
block-spring system comes to equilibrium as shown in figure (b).
Determine the elongation ΔL of the spring.

A 28 kg block on a horizontal surface is attached to a
horizontal spring of spring constant k = 4.8 kN/m. The block is
pulled to the right so that the spring is stretched 7.2 cm beyond
its relaxed length, and the block is then released from rest. The
frictional force between the sliding block and the surface has a
magnitude of 37 N. (a) What is the kinetic energy of the block when
it has moved 1.6 cm from...

A 220 g stone is dropped onto a relaxed vertical spring that
has a spring constant of k = 4.5 N/cm. The stone becomes attached
to the spring and compresses the spring 17 cm before momentarily
stopping. While the spring is being compressed, what work is done
on the stone by (a) the gravitational force on it and (b) the
spring force? (c) What is the speed of the stone just before it
hits the spring? (Assume no friction) (d)...

13.5 A spring with a spring constant of 450 N/m is stretched 20
cm from the equilibrium position. a) What is the magnitude of the
spring force at x = 20 cm? b) If a 5 kg mass is attached to the
spring, what will the maximum acceleration be if the spring is
released from the x = 20 cm stretched position? c) Will the
acceleration be the same as the spring passes the x = 10 cm
position? If...

A horizontal spring attached to a wall has a force constant of
k = 820 N/m. A block of mass m = 1.20 kg is
attached to the spring and rests on a frictionless, horizontal
surface as in the figure below
(a) The block is pulled to a position xi =
5.40 cm from equilibrium and released. Find the potential energy
stored in the spring when the block is 5.40 cm from
equilibrium.
(b) Find the speed of the block...
