QUESTION 4 One can measure the speed v of a bullet by using a ballistic pendulum. Let the mass of the bullet m=15g. The mass of the wooden pendultom is M=7 kg. The bullet is shot, and the system made of Wood + Bullet start swinging with an initial velocity V upward, as much as h=5 cm. a) (15 p) Via using the law of energy conservation and the law of linear momentum conservation, find the initial velocity of the...

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...

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...
If you fire a bullet at a speed vi,bullet = 400 m/s into a wooden block...
If you fire a bullet at a speed vi,bullet = 400 m/s into a wooden block of mass 0.2 kg, and after the bullet embeds in the wood, the velocity of the bullet and block together is 7.8 m/s. What is the mass of the bullet? 4 g 6 g 2 g 0.2 kg What is conservation of momentum a special instance of? Newton's 2nd law, the momentum principle Newton's 1st law, the inertia principle Newton's 3rd law, the reciprocity...

A simple way to measure the speed of a bullet is with a ballistic pendulum. It consist of a block of mass suspended by a cable of length 'L' and swings an angle due to the bullet. the bullet has a mass and initial velocity . The bullet is completely absorbed by the block, and there is no external force so momentum is conserved. a) Why is Energy NOT conserved? b) Once the bullet is lodged in the block, energy...

1. A 35 g bullet is fired into the bob of a ballistic pendulum of mass 4.75 kg. When the bob is at its maximum height, the string makes an angle of 55 with the vertical. The length of the pendulum is 4.0 m. Find the speed of the bullet before impact. (Hint: Consider Momentum and Energy Conservation)

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...

A bullet with some mass, m, and initial speed, vi, collides with a wooden block of mass M that is hanging at the end of a light rope. The bullet imbeds itself in the block and the block and bullet swings upwards reaching a maximum height of h above the initial point of the collision. a. A scientist can measure the masses and the height, show that the initial speed can then be calculated from the following equation: vi= (m+M)/m×root...
