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 particle with a speed of 1.8 x 107 m/s.What is the recoil speed of the remaining radon atom? The thorium nucleus mass is 3.8 x 10-25 kg, and the alpha‐particle (Helium nucleus) mass is 6.68 x 10-27 kg.

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...
15-39. A ballistic pendulum consists of a wooden block originally at rest =0" When a 2-3 bullet strikes and becomes embedded in it, it is observed that the Mack swings upward to a maximum angle of = 6° Estimate the speed of the bullet SOLUTION
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...
Dr. O fires a 30.0g bullet into the block of a ballistic pendulum. The bullet embeds in the block. The initial speed of the bullet is 235 m/s.

Please write clearly and each step. Thanks! Ballistic Pendulum– A 2.50 kg block of wood is suspended from the ceiling with a 0.6m length of wire of negligible mass. A bullet, whose mass is 10g, is fired into the block, and together they swing with an initial speed of 1.2 m/s. Ignore the effects of air resistance. a. What is the velocity of the bullet immediately before it hits the block? b. What is the magnitude of the average force...
A bullet of mass 4.5 g strikes a ballistic pendulum of mass 1.7 kg. The center of mass of the pendulum rises a vertical distance of 6.3 cm. Assuming that the bullet remains embedded in the pendulum, calculate the bullet's initial speed.
A bullet of mass 3.1 g strikes a ballistic pendulum of mass 2.7 kg. The center of mass of the pendulum rises a vertical distance of 6.1 cm. Assuming that the bullet remains embedded in the pendulum, calculate the bullet's initial speed.
A bullet of mass 2.9 g strikes a ballistic pendulum of mass 4.7 kg. The center of mass of the pendulum rises a vertical distance of 15 cm. Assuming that the bullet remains embedded in the pendulum, calculate the bullet's initial speed.
A 10.0 g rifle bullet is fired with a speed of 370 m/s into a ballistic pendulum with mass 7.00 kg , suspended from a cord 70.0 cm long. A) Compute the initial kinetic energy of the bullet; B) Compute the kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum. C) Compute the vertical height through which the pendulum rises.
