Question

In a ballistic pendulum, a bullet of mass m = 5.50 g is fired with an initial speed v0 = 550 m/s at the bob of a pendulum. The bob has mass M = 2.00 kg, and suspended by a rod of negligible mass. After the collision, the bullet and bob stick together and swing through an arc, eventually gaining a height h. (a) Please find the h. (b) Please find the kinetic energy of the system before the collision and after the collision. (Hint: Use momentum conservation law for the collision process, and then use energy conservation law for the swing process)

Answer #1

Suppose a bullet of mass m = 6.72 g is fired into a ballistic
pendulum whose bob has a mass of M = 0.625 kg. If the bob rises to
a height of 0.148 m, what was the initial speed of the bullet?

2. In a “ballistic pendulum,” the bullet is fired at a massive
pendulum bob that is hanging straight downward at rest. The bullet
embeds itself in the bob, and the bob+bullet together swing up to
some maximum height before pausing to swing back downward.
a.) If the bullet has a mass of 30. g, the bob’s mass is 5.0 kg,
and the bob+bullet reaches a final height of 50. cm after impact,
what is the speed of the bullet just...

A 17 g bullet is fired into the bob of a ballistic pendulum of
mass 1.3 kg. When the bob is at its maximum height, the strings
make an angle of 60° with the vertical. The length of the pendulum
is 2.3 m. Find the speed of the bullet.
_____m/s

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

5. A bullet with a mass 0.850 g is fired in to a hanging block
which is free to swing (recall ballistic pendulum). Mass of the
hanging block is 6.4 kg. The bullet comes to rest as it is fired to
the block and the block + bullet then swing upward vertically
displacing the center of mass of the system by 7. 2 cm before the
system comes momentarily to rest at the end of the arc. What is the...

a ballistic pendulum is a device used to measure the speed of a
bullet. A bullet of mass m = 50g is fired at a block of wood (mass
m =750g) hanging from a string. The bullet embeds itself in the
block, and causes the combined block plus bullet system to swing up
a height h=0.45m. What is the initial speed of the bullet before it
hits the block?

In
a ballistic pendulum, a 1 kg mass is fired at a speed of 17 at a
stationary pendulum of mass 7. If the bullet becomes trapped inside
the pendulum after the collision, determine the maximum height to
which the pendulum will rise?

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...

A 7.00 g bullet is fired into a ballistic pendulum with length
of 82 cm and mass of 0.95 kg. If the pendulum then rises to an
angle of 5.40, what was the initial speed of the bullet?
can you please show in detail how you worked the problem

in a ballistic pendulum, a fast moving bullet with a mass of 5g
is fired into a hanging wood with a mass of 1kg at rest. if the
hanging mass with the bullet inside it rose to a vertical height of
5 cm, find the initial velocity of the bullet.
