a ballistic pendulum consists of a block of weed suspended by chords. when a bullet is fired into the block it is free to rise. how high does a 2kg block rise when 10gram bullet is traveling at 300 m/sec? show work
Homework Answers
I am assuming block stick with weed and rises with it.
Use conservation of energy:
Initial kinetic energy = final potential energy
0.5*m1*v^2 = (m1+m2)*g*h
0.5*0.01*(300)^2= (0.01+2)*9.8*h
h=22.8 m
Answer: 22.8 m

A ballistic pendulum is a device for measuring bullet speeds. One of the simplest versions consists of a block of wood hanging from two long cords. (Two cords are used so that the bottom face of the block remains parallel to the floor as the block swings upward.) .013-kg bullet traveling at 320 m/s hits a 3.0-kg ballistic pendulum. However, the block is not thick enough for this bullet, and the bullet passes through the block, exiting with one-third of...

The ballistic pendulum is a simple device—the pendulum part consists of a wooden block, which has a mass of 860. grams, hanging from a string. The block is initially at rest. However, a bullet with a mass of 18.0 grams is fired at the block. The bullet embeds itself in the block, and the bullet and block then oscillate back and forth on the string, pendulum style, after the collision. Just before impact with the block, the bullet's velocity is...

simple way to measure the speed of a bullet is with a ballistic pendulum, which consists of a wooden block of mass m into which a bullet of mass m, is shot. The block is suspended from two cables, each of length L. Assume that the time the bullet takes to come to rest (that is, the bullet is moving at the same speed as the block) is negligibly Small. The impact of the bullet causes the block and embedded...

A ballistic pendulum is used to measure the speed of bullets. In these experiments, a bullet is fired into a large block suspended by wires. The bullet is embedded in the block and the collision is inelastic. After the impact, the block swings forward and rises. a. If a 2.1-g bullet is fired at 440 m/s into a 4.0 kg block, how far will it swing up? (what is the maximum vertical displacement of the block?) b. Find an equation...

In a ballistic pendulum, a bullet of mass m is fired into a stationary hanging block of mass M. On impact, the bullet is trapped inside the block, which then slides up to a maximum height of h = 4.06 cm. If the mass of the block (M) is 4.7 times larger than the mass of the bullet (m), determine the speed v which the bullet must have had prior to impact.

A bullet of mass 8 g is fired into a 1.2 kg ballistic pendulum (a block of wood acting as the pendulum bob of a thin metal arm attached to a low friction pivot point) that is initially at rest. The bullet exits the block of wood with a speed of 180 m/s and the wooden block swings from its lowest point to a maximum height of 9.2 cm above that location. Determine the velocity of the bullet before it...

Please write clearly and each step. Thanks! Ballistic Pendulum– A 2.50 kg block of wood is suspended from the ceiling with a 0.6m length of wire of negligible mass. A bullet, whose mass is 10g, is fired into the block, and together they swing with an initial speed of 1.2 m/s. Ignore the effects of air resistance. a. What is the velocity of the bullet immediately before it hits the block? b. What is the magnitude of the average force...
