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 that will solve for the velocity of the bullet in terms of m1 (bullet mass), m2 (block mass), and h (the height that the pendulum swings to). c. Use your equation from part b to solve for the bullet velocity in the following experiment: a 7.5 g bullet fired into a 20.0-kg block that swings up to a height of 10.3 cm.

    A ballistic pendulum is a device that is used to determine the muzzle velocity of the bullet shot by a hunting rifle, for example. As you know, the velocity of the bullet fired by a rifle dictates the distance it can travel. Those who reload their own bullets may find this device helpful. When a bullet is fired broadside into a suspended 4x4 chunk of wood, the wood swings up from rest by an angle of 60 degrees. Together, the...

    The ballistic pendulum is an apparatus used to measure the speed of a fast-moving projectile such as a bullet. A projectile of mass ml-20 g (vl-30 m/s) is fired into a large block of wood of mass m2-40 g suspended from some light wires. The projectile cmbeds in the block, and the entire system swings through a height h. How can we determine the height h? VIA St

    3. The ballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. The projectile, of mass m, is fired into a large block of mass M, which is suspended like a pendulum. As a result of the collision, the pendulum and projectile together swing up to a maximum height h. Determine the relationship between the initial horizontal speed of the projectile, v, and the maximum heighth

    A ballistic spring system can be used to measure the speed of bullets. A bullet of mass 0.005 kg is fired into a block of mass 2 kg. The block, with the embedded bullet, then slides across a frictionless table and collides with a horizontal spring whose spring constant is 50 N m . The opposite end of the spring is anchored to a wall. The spring’s maximum compression is measured to be 0.1 m. Calculate the initial speed of...
