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.

    Question 1 5 pts 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 - 11.26 cm. If the mass of the block (M) is 2.3 times larger than the mass of the bullet (m), determine the speed v which the bullet must have had prior to impact. M+m m

    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...

    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)

    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...

    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
