A thin, uniform, rectangular sign hangs vertically above the door of a shop. The sign is hinged to a stationary horizontal rod along its top edge. The mass of the sign is 2.40 kg and its vertical dimension is 75.0 cm. The sign is swinging without friction, becoming a tempting target for children armed with snowballs. The maximum angular displacement of the sign is 25.0° on both sides of the vertical. At a moment when the sign is vertical and moving to the left, a snowball of mass 500 g, traveling horizontally with a velocity of 160 cm/s to the right, strikes perpendicularly the lower edge of the sign and sticks there. (a) Calculate the angular speed of the sign immediately before the impact.. rad/s (b) Calculate its angular speed immediately after the impact. rad/s (c) The spattered sign will swing up through what maximum angle?

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...
A 0.00600 kg bullet traveling horizontally with speed 1.00 103 m/s strikes a 20.8 kg door, embedding itself 11.0 cm from the side opposite the hinges as shown in the figure below. The 1.00 m wide door is free to swing on its frictionless hinges.What is the angular momentum? At what angular speed (rad/s) does the door swing open immediately after the collision? Calculate the total energy of the bullet-door system and determine whether it is less than or equal...
A horizontal vinyl record of mass 0.0856 kg and radius 0.0898 m
rotates freely about a vertical axis through its center with an

A uniform thin rod of length 50 cm and mass 4.0 kg can rotate in a horizontal plane about a vertical axis through from the right side. The rod into one end of the rod. As viewed from above, the bullet's path makes an angle of θ 60° with the rod (as shown in the figure below)If the bullet lodges in the rod and the angular velocity of the rod is 10 rad/s immediately after the collision, what is the...
A particular horizontal turntable can be modeled as a uniform disk with a mass of 180 g and a radius of 30.0 cm that rotates without friction about a vertical axis passing through its center. The angular speed of the turntable is 2.00 rad/s. A ball of clay, with a mass of 40.0 g, is dropped from a height of 35.0 cm above the turntable. It hits the turntable at a distance of 15.0 cm from the middle, and sticks...
Shown below is a small particle of mass 19 g that is moving at a speed of 10 m/s when it collides with and sticks to the edge of a uniform solid cylinder. The cylinder is free to rotate about the axis through its center and perpendicular to the page. The cylinder has a mass of 0.4 kg and a radius of 20 cm and is initially at rest. 10 m/s Before After (a) What is the angular velocity (in...
Chapter 11, Problem 053 GO A uniform thin rod of length 0.61 m and mass 3.3 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is at rest when a 4.4 g bullet traveling in the rotation plane is fired into one end of the rod. As viewed from above, the bullet's path makes angle 9 -60° with the rod. If the bullet lodges in the rod and the angular velocity of the...
