Question

A block with a mass of 0.300 kg attached to one end of a spring can oscillate on a frictionless, horizontal surface. Initially the block is displaced 0.120 m from its equilibrium position and then it is released. After 0.152 s the block has not passed through the equilibrium position and is located 0.0371 m from its equilibrium position. Determine the spring constant of the spring.

Answer #1

If a 1 kg object on a horizontal, frictionless surface is
attached to a spring, displaced, and then released, it will
oscillate. If it is displaced 0.120 m from its equilibrium position
and released with zero initial speed. After 0.8 s its displacement
is found to be 0.120 m on the opposite side, and it has passed the
equilibrium position once during this interval. Find the amplitude,
the period, the frequency, the angular frequency and the spring
constant.

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 block of mass 2.00 kg is attached to a horizontal spring
with a force constant of 500 N/m. The spring is stretched 5.00 cm
from its equilibrium position and released from rest. Use
conservation of mechanical energy to determine the speed of the
block as it returns to equilibrium
(a) if the surface is frictionless
(b) if the coefficient of kinetic friction between the block and
the surface is 0.350

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 block with mass 0.382 kg is attached to a horizontal spring
with spring constant k = 1.28 N/m on a frictionless surface. The
block is pulled 0.753 m from equilibrium and released. (a) What is
the amplitude of the block's motion? (b) What is its period? (c)
How long after release does the block take to first return to its
equilibrium position? (d) What is its speed at that position? {b.
3.43 s, d. 1.38 m/s}
a) A=0.753m
b)...

A spring is attached to a wall, and a 0.50 kg block is attached
to the other end of the spring. The spring-block system sits on a
frictionless surface so that the block is able to oscillate without
losing energy. The spring constant of the spring is k = 25 N/m. The
block is pushed so that it compresses the spring by 20 cm beyond
its equilibrium position. The block is released from rest at
exactly the same time as...

A 4.37 kg block free to move on a horizontal, frictionless
surface is attached to one end of a light horizontal spring. The
other end of the spring is fixed. The spring is compressed 0.117 m
from equilibrium and is then released. The speed of the block is
1.01 m/s when it passes the equilibrium position of the spring. The
same experiment is now repeated with the frictionless surface
replaced by a surface for which uk = 0.345. Determine the...

A 0.0392-kg bullet is fired horizontally into a 2.04-kg wooden
block attached to one end of a massless, horizontal spring
(k = 838 N/m). The other end of the spring is fixed in
place, and the spring is unstrained initially. The block rests on a
horizontal, frictionless surface. The bullet strikes the block
perpendicularly and quickly comes to a halt within it. As a result
of this completely inelastic collision, the spring is compressed
along its axis and causes the...

A block of mass m = 0.79 kg is attached to a spring with force
constant 123.0 N/m. The block is free to move on a frictionless,
horizontal surface as shown in the figure. The block is released
from rest after the spring is stretched a distance A = 0.10 m to
the right. What is the potential energy of the spring/block system
0.25 s after releasing the block?

A 0.50 kg mass sliding on a horizontal frictionless surface is
attached to one end of a horizontal spring (with k = 325 N/m) whose
other end is fixed. The mass has a kinetic energy of 16.0 J as it
passes through its equilibrium position (the point at which the
spring force is zero). At what rate is the spring doing work on the
mass as the mass passes through its equilibrium position?
At what rate is the spring doing...
