Question

In a "ballistic pendulum" a bullet hits a pendulum which is initially at rest. After the collision the pendulum with the bullet embedded in it rises until it comes to rest. Which one of these is correct? (Neglect air resistance and friction in the suspension of the pendulum.)

The mechanical energy is conserved during the collision.

The mechanical energy is conserved during the swing.

The momentum is conserved during the swing.

Both the momentum and the mechanical energy are conserved during
the swing. Both the momentum and the mechanical energy are
conserved during the collision.

Answer #1

A bullet of mass 9.00 g is fired into a ballistic pendulum of
mass 4.90 kg. The pendulum rises a vertical height 0.0940 m.
Compute...
(a) the kinetic energy of bullet and pendulum after the bullet
is embedded in the pendulum before it has risen. J?
(b) the initial momentum of the bullet. kg·m/s ?
(c) the initial speed of the bullet. m/s

Revisiting the ballistic pendulum. In lab we used both
conservation of momentum and conservation of energy to relate the
launch speed of a projectile to the maximum height of the swing of
a pendulum. Here we will study the parts of this problem in a bit
more detail.
(a) Briefly explain why momentum is conserved during the
collision of the projectile and the pendulum, but mechanical energy
is not conserved.
(b) Briefly explain why mechanical energy (kinetic plus
potential energy)...

Can someone explain:
The ballistic pendulum is an apparatus used to measure the speed
of a projectile. An 8.0 g bullet is fired into a 2.5 kg ballistic
pendulum bob, which is initially at rest, and becomes embedded in
the bob. The pendulum then rises to a vertical distance of 6.0 cm.
What was the initial speed of the bullet (in m/s)?

In a ballistic pendulum experiment, a small marble is fired into
a cup attached to the end of a pendulum. If the mass of the marble
is 0.0295 kg 0.0295 kg and the mass of the pendulum is 0.250 kg
0.250 kg , how high will the pendulum swing if the marble has an
initial speed of 5.45 m/s 5.45 m/s ? Assume that the mass of the
pendulum is concentrated at its end so that linear momentum is
conserved...

A
ballistic pendulum is made from a block of m=3kg suspended by a
wire of negligible mass. A bullet of m=2g is fired with a speed of
v. The bullet collides with the block and is embed inside the
block. r
Right after collision, the block with the bullet unside has a
speed of v' and swings to a max height of 0.85m above the initial
position.
a) Find an expression for V.
b) Find an expression for the energy...

A 30-g riffle bullet traveling 250 m/s buries itself in a 4 kg
pendulum hanging on a 3 m long string, which makes the pendulum
swing upward in an arc. Ignoring friction and air resistance, what
angle will the pendulum make with the vertical at the peak of its
swing?

A 12.0g bullet is fired horizontally into a 650g block that is
initially at rest on a frictionless horizontal surface. The initial
velocity of the bullet is 450m/s. After the bullet is embedded into
the block, the bullet-block system slides along the frictionless
surface into a spring having spring constant k=470N/m
a. What is the speed of the block after the bullet once it’s
stuck in the block
b. What was the work done on the bullet during the collision...

3)A bullet hits a hanging plate target at rest. The bullet gets
stuck on the target and the plate's center of mass gets raised to a
height h. Consider no friction at the hanging point of the target.
which statement is true?
a)The initial kinetic energy of the bullet is less than the
gravitational potential energy of the plate at height h. b) The
initial kinetic energy of the Buller is greater than the
gravitational potential energy of the plate...

A ballistic pendulum is a device used to measure the speed of a
projectile of mass m (at point A). The projectile is launched
horizontally into a target of mass M which is suspended like a
pendulum (point b). When the projectile strikes the target it
imbeds. The maximum height reached by the pendulum and projectile
together is then measured (point c).
. -find the equation describing the collision from point
a-->b. (conservation of momentum)
- find equation describing the...

a small bullet of mass m= 6 g staright up collides which a
massive block of wood. At the time of impact of the speed of the
bullet is V_i = 8 m/s. The block has a mass m= 5 kg and is
initially vest on the table as shown in the picture. In the
collision the bullet gets embeded in the block. After the collision
the block and bullet system rises up to a maximum height H. The
collision...
