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...

The top edge of a thin rectangular metal plate with a mass of 2.80 kg is attached to a horizontal rod parallel to the edge of the plate. The plate hangs from this rod and is free to rotate about it without friction. The vertical height of the plate is 45.0 cm. The plate is pulled to the right until it makes an angle of 28.0° from vertical and then released from rest. At the same time, a piece of...
Two disks collide with the initial velocities just before the collision as shown in (Figure 1).
Learning Goal: To use the conservation of momentum and the coefficient of restitution to determine the speeds of two disks after a collision Two disks collide with the initial velocities just before the collision as shown in (Figure 1). What are the speeds of the two disks just after impact if the coefficient of restitution is e = 0.9? The masses of the disks are mA = 5 kg and mB = 7.5 kg, the initial velocities are vA = 3...

A steel ball of mass m = 1 kg and a cord of negligible mass and
length L = 2 m make up a simple pendulum that can pivot without
friction about the point O (see below). This pendulum is released
from rest in a horizontal position and when the ball is at its
lowest point it strikes a block of mass m = 1 kg sitting at rest on
a shelf. Assume that the collision is perfectly elastic and...

A pendulum bob, with mass 1.60 kg, is held at rest initially in a horizontal position as shown. The string has negligible mass and a length of 1.20 m. The bob is then released from rest. It swings down and collides with a block of mass 2.40 kg initially at rest. Ignore air resistance. a) Use the Principle of Conservation of Mechanical Energy to find the speed of the pendulum bob just before the collision. b) (The bob collides with...

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...

A pendulum, consisting of a ball of mass m on a light
string of length 1.00 m, is swung back to a 45° angle and released
from rest. The ball swings down and, at its lowest point, collides
with a block of mass 2mthat is on a frictionless
horizontal surface.
Note that you will most likely get different numbers for the
different parts below. As usual, a good way to handle that is to
solve the problem using variables, and...

b) Disk A in Fig B2b has a mass of 2 kg and is sliding forward on the smooth surface with a velocity (%),-5 m/s when it strikes the 4 kg disk B. Disk B is coefficient of restitution between the disks is e0.4, compute the velocities of A and B just after collision. Hint Coefficient of restitution is defined as e where indices 1 and 2 mark velocities before and after impact respectively. Je Fig. B2b [8 marks]
