Question

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?

Answer #1

The answer : Initial velocity of Bullet before it hits the block is 48m/s.

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...

In a ballistic pendulum, a 1.25-g bullet is shot straight into
and becomes stuck in a 5.00-kg wood block which is hanging from a
1.4 m long string. This causes the block to swing up to an angle of
2.5°. What was the speed of the bullet just before it hit the
block?

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.

In a device called the ballistic pendulum, a compressed spring
is used to launch a steel ball horizontally into a soft target
hanging from a string. The ball embeds in the target and the two
swing together from the string. Describe the energy transfers
and/or transformations that take place during the use of the
ballistic pendulum and at what points they occur.

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...

A bullet of mass m = 2.40×10-2 kg is fired along an incline and
embeds itself quickly into a block of wood of mass M = 1.35 kg. The
block and bullet then slide up the incline, assumed frictionless,
and rise to a height H = 1.35 m before stopping. Calculate the
speed of the bullet just before it hits the wood.

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)?

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...

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 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
