A horizontal spring attached to a wall has a force constant of
760 N/m. A block of mass 1.30 kg is attached to the spring and
oscillates freely on a horizontal, frictionless surface as in the
figure below. The initial goal of this problem is to find the
velocity at the equilibrium point after the block is released.
(c) Find the energy stored in the spring when the mass is
stretched 5.80 cm from equilibrium and again when the mass...

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.)
The left end of a horizontal spring is attached to a vertical
wall, and...

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...

6) A mass of 3 kg is attached to a massless spring with
a force constant 500 N/m. The mass rests on a horizontal
frictionless surface. The system is compressed a distance of 30 cm
from the springs initial position and then released. The momentum
of the mass when the spring passes its equilibrium position
is?
8660.25m/s
Is this right

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 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-spring system consists of a spring with constant
k = 445 N/m attached to a 2.25 kg block on a frictionless
surface. The block is pulled 4.10 cm from equilibrium and released
from rest. For the resulting oscillation, find the amplitude,
angular frequency, frequency, and period. What is the maximum value
of the block's velocity and acceleration?

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...

An 81.9 g mass is attached to a horizontal spring with a spring
constant of 3.5 N/m and released from rest with an amplitude of
39.1 cm. What is the speed of the mass when it is halfway to the
equilibrium position if the surface is frictionless? Answer in
units of m/s.
