A professor's office door is 0.95 m wide, 2.2 m high, 4.2 cm thick; has a mass of 30 kg , and pivots on frictionless hinges. A "door closer" is attached to door and the top of the door frame. When the door is open and at rest, the door closer exerts a torque of 5.0 N⋅m .
Part A: What is the moment of inertia of the door?
Part B:
If you let go of the open door, what is its angular acceleration immediately afterward?

Josh's office door is 0.82 m wide, 6.0 cm thick, and 2.10 m high. The door has a mass m = 15.0 kg and pivots on frictionless hinges. A door closer is attached to the door and the top of the door frame. When the door is open and at rest, the door closer exerts a torque Γ = 4.50 N m. What is the smallest force that you need to apply to the door to hold it open? Enter your...
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.
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 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...
