ch05prob5.58

A system consists of a 4.6-kg cart and a 1.4-kg cart attached to
each other by a compressed spring. Initially, the system is at rest
on a low-friction track. When the spring is released, an explosive
separation occurs at the expense of the internal energy of the
compressed spring. The change in the spring's internal energy
during the separation is 1.0

kJ

.

Answer #1

A system consists of a 4.0-kg cart and a 1.2-kg cart attached to
each other by a compressed spring. Initially, the system is at rest
on a low-friction track. When the spring is released, an explosive
separation occurs at the expense of the internal energy of the
compressed spring. The change in the spring's internal energy
during the separation is 1.0 kJ. What is the speed of 1.2-kg cart
right after the separation? What is the speed of 4.0-kg cart...

A small cart of mass 0.8 kg is attached to one end of a
massless, horizontal spring as shown in the figure. The spring
constant is 600 N/m. The spring is stretched by 0.05 m and the cart
is released from rest. The cart then oscillates back and forth
undergoing simple harmonic motion. Friction and air resistance are
negligible.
a) (5 pts) Find the angular frequency ω of the motion.
b) (5 pts) How long does it take for the...

A cart with a total mass of 300g is on low-friction track with a
string attached to mass of 100g hanging over a low friction pulley?
The cart and hanging weight are held in place and then released. 1.
what is the acceleration of the cart after it is released Express
your answer in SI units keeping the correct number of significant
figures.

A cart of mass m = 1.2 kg is placed on a horizontal track. The
cart rolls with very little friction, and is attached to the left
end of the track by a spring with negligible mass, spring constant
k = 20.0 N/m, and un-stretched length 25.0 cm.
(A) The cart is moved 7.5 cm to the left of its equilibrium
position, and is then released from rest. Draw a sketch of the
position x along the track of the...

A 0.150-kg cart is attached to an ideal spring with a force
constant of (spring constant) of 3.58 N/m undergoes simple harmonic
motion and has a speed of 1.5 m/s at the equilibrium position. At
what distance from the equilibrium position are the kinetic energy
and potential energy of the system the same?

A spring-mass system consists of a 0.5 kg mass attached to a
spring with a force constant of k = 8 N/m. You may neglect the mass
of the spring. The system undergoes simple harmonic motion with an
amplitude of 5 cm. Calculate the following: 1. The period T of the
motion 2. The maximum speed Vmax 3. The speed of the object when it
is at x = 3.5 cm from the equilibrium position. 4. The total energy
E...

A 2.90 kg block on a horizontal floor is attached to a
horizontal spring that is initially compressed 0.0340 m . The
spring has force constant 850 N/m . The coefficient of kinetic
friction between the floor and the block is 0.42 . The block and
spring are released from rest and the block slides along the
floor.
Part A
What is the speed of the block when it has moved a distance of
0.0190 m from its initial position?...

A mass of 0.5 kg is attached to a spring whose k=8000 N/m. The
system rests on a
level friction-free air track and is initially at rest. A second
mass makes a head-on
elastic collision with the mass attached to the spring; thereafter
the oscillating
system vibrates with amplitude of 0.5 m. If the incident mass is
0.4 kg, what was its
incident speed?

A 0.500-kg mass attached to an ideal massless spring with a
spring constant of 12.5 N/m oscillates on a horizontal,
frictionless surface. At time t = 0.00 s, the mass is
located at x = –2.00 cm and is traveling in the positive
x-direction with a speed of 8.00 cm/s.
PART A: Find the angular frequency of the oscillations. Express
your answer in rad/s.
PART B: Determine the amplitude of the oscillations. Express
your answer with the appropriate SI units....

Mazur 9.40: Two identical 0.50 kg carts, each 0.10 m long, are
at rest on a low-friction track and are connected by a spring that
is initially at its relaxed length of 0.50 m and is of negligible
inertia. You give the cart on the left a push to the right (that
is, toward the other cart), exerting a constant 5.0-N force. You
stop pushing at the instant when the cart has moved 0.40 m. At this
instant, the relative...
