A driver starts his car with the door on the passenger's side wide open (0 = 0). The 100-b door has a centroldal radius of gyration k =12 in., and its mass center is located at a distance r = 20 in. from its vertical axis of rotation. Determine the smallest constant acceleration that the driver can maintain if the door is to close and latch, knowing that as the door hits the frame its angular velocity must be at...

A uniform door initially at rest has a width W = 1.5m and mass M= 20 kg. The door is hinged on one side and can freely rotate about the hinges without friction. A policeman fires a bullet, m, = 15 g into the door at a speed v. = 500m/s. The bullet takes a horizontal path and strikes the door in a perpendicular direction at the exact center. The moment of inertia of the door about an axis passing...

A 0.00600-kg bullet traveling horizontally with a speed of 1.00 103 m/s enters a 17.5-kg door, embedding itself 20.0 cm from the side opposite the hinges as in the figure below. The 1.00-m-wide door is free to swing on its hinges. A) At what angular speed does the door swing open immediately after the collision? (The door has the same moment of inertia as a rod with axis at one end.) B) Calculate the energy of the door-bullet system and...

Complete the 2 questions below. Question 1 Axle A disk is attached to an axle, about which it can freely rotate without friction. The axle is parallel to the floor, and the disk has a mass of 4.30 kg and a diameter of 25.6 cm. The disk is held so that its centre of mass is as high as the axle, and then released from rest. What is the angular velocity of the...
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. The 1.00 m wide door is free to swing on its frictionless hinges.

Suppose that the rod is held at rest horizontally and then released. (Throughout the remainder of this problem, your answer may include the symbol I, the moment of inertia of the assembly, whether or not you have answered the first part correctly.) What is the angular acceleration ? of the rod immediately after it is released? Take the counterclockwise direction to be positive. Express ? in terms of some or all of the variables mr, m1, m2, x, I, and...
