A pencil (mass 12.0 g and length 18 cm) is initially balanced so that it is sitting vertically on a flat table. If the pencil then falls, what is its angular velocity just before it strikes the tabletop? Assume the mass of the pencil is distributed uniformly and the end of the pencil in contact with the table does not slip.

A pencil (mass 12.0 g and length 18 cm) is initially balanced so that it is standing vertically on a flat table. If the pencil then falls, what is its angular velocity just before it strikes the tabletop? Assume the mass of the pencil is distributed uniformly and the end of the pencil in contact with the table does not slip.

Q19: The uniform rod of mass M- 2 kg and length of L- 8 cm is free to rotate about a horizontal axis shown in the figure. An object of mass 0.4 kg moving with 24 m/s strikes and then sticks to the initially stationary rod as shown. If rotational inertia of the rod according to its center of mass is given as Icmdisk M, find the a) rotational inertia of the system before and after collision, b) angular speed...

A disk of mass m, = 70.0 g and radius r , = 4.50 cm slides on a frictionless sheet of ice with velocity v, where v = 12.00 m/s, as shown in a top-down view in figure (a) below. The edge of this disk just grazes the edge of a second disk in a glancing blow. The second disk has a mass m2 = 140 g, a radius r2 = 6.00 cm, and is initially at rest. As the...

A 14 g bullet is fired at 436.9 m/s into a solid cylinder of mass 26.5 kg and a radius 0.28 m. The cylinder is initially at rest and is mounted on fixed vertical axis that runs through it's center of mass. The line of motion of the bullet is perpendicular to the axle and at a distance 8.3 cm from the center. What is the initial angular momentum of the system? Find the angular velocity of the system after...

Problem: (2 Parts) Consider a stick of mass, M = 12.0 kg and length, L = 1.70 m hanging vertically initially. A bullet of mass, m = 0.030 kg and speed, v = 50 m/s strikes and embeds itself at the bottom end of the stick. Magnitude of acceleration due to gravity is g = 10 m/s2. Note: The moment of inertia of a rod about it's center of mass I = 1 ML?. You may need to use the...

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...
