Question

A 1.2 kg mass attached to a spring (150 N/m) is pulled 12cm to the side and released. how far is the spring from its equilibrium length when the mass has half its maximum speed?

Answer #1

A
0.300 kg mass is attached to a 26.6 N/m spring. It is pulled 0.120
m and released. How much potential energy does it have when it is
0.0600 m from equilibrium? (Unit = J)

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) maximum speed of the oscillating mass
b) speed of the oscillating mass when the spring is compressed
1.5 cm
(c) speed of the oscillating mass as it passes the point 1.5 cm
from the equilibrium position

A 4 kg mass is attached to a spring with stiffness 48 N/m. The
damping constant for the spring is 16\sqrt{3} N - sec/m. If the mas
is pulled 30 cm to the right of equilibrium and given an initial
rightward velocity of 3 m/sec, what is the maximum displacement
from equilibrium that it will attain?

A 3.70 kg mass is attached to a spring with a spring constant of
4.06 N/m
. It is initially
lifted away from its equilibrium position by 0.200 m in the
positive direction and
released from rest.

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.

A block of mass m = 2.00 kg is attached to a spring of force
constant k = 600 N/m as shown in the figure below. The block is
pulled to a position xi = 5.35 cm to the right of equilibrium and
released from rest. (a) Find the speed the block has as it passes
through equilibrium if the horizontal surface is frictionless. m/s
(b) Find the speed the block has as it passes through equilibrium
(for the first...

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...
