3. A ballistic pendulum is used to measure the speed of a bullet. It consist of a block of wood (mass=2.50 kg) suspended by a wire of negligible mass. A bullet (mass=D0.0100 kg) is fired with a speed Vb1 into the block. Just after the bullet collides with it, the block (with the bullet) has a spee V2 and then swings to a maximum height of 0.650 m above the initial position. Find the speed of the bullet. (Hint: Use LCM.)

A 12.0-g bullet is fired horizontally into a 114-g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring having spring constant 143 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 82.0 cm, what was the speed of the bullet at impact with the block? m/s

Two metal spheres are suspended by vertical cords as shown below. Sphere 1, m = 25g, is pulled to a height hị = 8.0cm and then released from rest. After swinging down, it undergoes an elastic collision with sphere 2, m2 = 80g. What is the velocity of sphere 1 right after the collision? To what height will sphere 2 rise?

A 33.7-g rifle bullet traveling 205. m/s buries itself in a 2.97-kg pendulum hanging on a 2.67-m-long string, which makes the pendulum swing upward in an arc. Determine how high (in m) the pendulum swings above its original position.

. What is the initial kinetic energy in joules of the bullet in problem 1? What is the final kinetic energy of the combined bullet/pendulum?

Plz give me the advanced Physics solution.

1. Physics Problem: 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 (see the Figure below). 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, vo, and the maximum height h. Determine the percentage energy loss in the inelastic collision. 2. The ballistic pendulum device will be demonstrated in class. 3. Fire the ballistic pendulum five times and record the pendulum's maximum height after each round. 4. Remove the pendulum arm from the ballistic pendulum. Mass the pendulum arm and the projectile separately. 5. Determine the average speed and the statistical error (standard deviation).

A mass m1 = 10.5 kg, with initial velocity V0 = 12.5 m/s, strikes a mass-spring system m2 = 7.25 kg, initially at rest but able to recoil. Assume the spring is massless and the surface horizontal and frictionless. See the figure below. If the collision is completely elastic, what are the final speeds V1 and V2 of m1 and m2, respectively?

A bullet, with mass 0.008 kg is fired into a block of wood with mass 1.96 kg suspended like a pendulum. The bullet makes a completely inelastic collision with the block, becoming embedded in it. After the impact of the bullet, the block swings up to a maximum height 0.079 m. Find the initial speed of the bullet? a) DVB V₂ Δε C M ب 6) /// hJ دو ► M+m

1. An inventor patents a "golf machine". It consists of a "golf club" which is really a pendulum of length L = 2 (m), with a massles string and a mass M = 30 (kg) on the end. By pulling back on the pendulum until the string makes an angle 0= 10° from the vertical, and then releasing it from rest, the golf club strikes the "golf ball" exactly horizontally. The golf ball is a mass m = 0.1 (kg) that rests on a platform which is h = 20 (cm) above the horizontal ground. Assume that all collisions are elastic and all masses are point masses. Finally you should ignore air resistance but gravity acts down as usual. L %3D M) m h How far does m travel horizontally (before it hits the ground)? |How long does it take from the time M is released from rest to the time it strikes m? [Hint: think pendulum]
