A physical pendulum consists of a vertical board of mass 5.37 kg, length 171 cm, and width 12 cm hanging from a horizontal, frictionless axle. A bullet of mass 149 g and a purely horizontal speed v impacts the pendulum at the bottom edge of the board. The board then makes a complete circle.
(a) If the bullet passed through the board, reducing its speed by a factor of 1/2, what is the minimum speed of the bullet?
(b) If the bullet embedded itself in the board, what is the minimum speed of the bullet?

A pendulum of a mass mp = 3.60 kg hanging at the bottom end of a massless rod of length ℓ = 0.60 m has a frictionless pivot at its top end. As shown in the above figure, a bullet of mass mb = 0.50 kg, moving with a horizontal velocity vb, impacts the pendulum and becomes embedded. The pendulum then swings to rest at its topmost position converting all of its kinetic energy into potential energy. (a) Use the...

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...

A conical pendulum consists of a mass hanging from a string while moving in a horizontal circle of radius r (see Figure 1; the blue arrow indicating velocity is pointing “into” the page, not up.). If the mass moves at constant speed 1.3 m/s and the angle the string does with the vertical is θ = 12◦ , what is the radius r of the circle? (Hint: This is similar to the “hanging chairs” problem from class.)

A pendulum of length L = 1.0 meter and bob with mass m = 1.0 kg is released from rest at an angle 0 = 30' from the vertical. When the pendulum reaches the vertical position, the bob strikes a mass M= 3.0 kg that is resting on a frictionless table that has a height h = 0.85m. (a). When the pendulum reaches the vertical position, calculate the speed of the bob just before it strikes the box. (6 marks]...

The assembly shown in the figure below consists of a thin rod of length l = 23.9 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top. The assembly is free to pivot about a frictionless axle through the bottom of the rod. The assembly is initially vertical and at rest when it starts to rotate clockwise. (a) After the combination rotates through 90...

1. A wooden rod of length 40.0 cm and mass 1.00 kg is sitting on a frictionless horizontal surface. The rod has a pin through its centre so that it can freely rotate about a vertical axis perpendicular to the rod and passing through the center of the rod. A projectile of mass 0.0100 kg is now shot at the rod. The projectile is moving horizontally with a speed of 2.00 x 102 m/s in the direction perpendicular to the...
