1) A ballistic pendulum consists of a 3.60 kg wooden block on the end of a long string. From the pivot point to the center‐of‐mass of the block is a distance of 2.80 m. With the pendulum hanging straight down, a rifle bullet of 28.0 g mass moving with a speed of 210 m/s embeds itself into the wood. To what maximum angle does the pendulum (with embedded bullet) swing upward? 2) The thorium‐228 nucleus decays by emitting an alpha...

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 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...

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...

A small wooden block with mass 0.775 kg is suspended from the lower end of a light cord that is 1.52 m long. The block is initially at rest. A bullet with mass 0.0136 kg is fired at the block with a horizontal velocity of 375 m/s . The bullet strikes the block and becomes embedded in it. After the collision the combined object swings on the end of the cord. The block and bullet rise so that the cord...

Problem 3 A "ballistic pendulum" is a device (now largely obsolete, but very useful in its day) to measure the speed of a bullet as it hits a target. Let the target be a block of wood suspended from a string, as in the figure below. When the bullet hits, it is embedded in the wood, and together they swing, like a pendulum, to some maximum height h. The question is, how do you find the initial speed of the...
