1. Find angular speed of door after
collision
2. What is the change in kinetic friction?
A 1.5m wide door (mass 15kg) is hinged at one side so that it can rotate without friction about a vertical axis. It is unlatched. A police officer fires a bullet with a mass of 10g and a speed of 400m/s into the exact center of the door, in a direction perpendicular to the plane of the door. Find the angular speed of the...
part c=d
How much force must you and your friend each apply to the free
end of the door on the same side and perpendicular to the plane of
the door in order to produce the same torque as that produced by
both of you in part (a) above?

A rotating door is made from four rectangular glass panes, as
shown in the figure. The mass of each pane is 96.2 kg. A person
pushes on the outer edge of one pane with a force of F = 125 N that
is directed perpendicular to the pane. Determine the magnitude of
the door's angular acceleration.
A rotating door is made from four rectangular glass panes, as
shown in the figure. The mass of each pane is 75.9 kg. A person
pushes on the outer edge of one pane with a force of F = 101 N that
is directed perpendicular to the pane. Determine the magnitude of
the door's angular acceleration.
Tran ties a string to a doorknob 0.70 m from the hinge as shown in the figure. The door is 0.80 m in length (l) and its mass (m) is 15 kg. The moment of inertia for the door is given by: Idoor = 1/3 ml2 . At the instant shown, the Robbie applies a 7.0 N force to the string. i. What is the torque on the door?Determine the angular acceleration of the door just as Tran pulls the...

Thanks in advance. I will rate up the correct answer, and down the
wrong one.
A heavy swing door has a mass of m = 4,000 kg, a width w = 1.0 m, and a height H = 2.7 m. The door swings about a vertical axis passing through its center. The moment of inertia of this door about the vertical axis of rotation is given by I = 1/12 mw^2. (a) You stand on one side and push...
A door shown in the figure) undergoes rotational motions about the vertical axis. The governing equation of rotational motion is given by Jyö + C70 + k 0 = 0 where Jo is the moment of inertia of the door, Ct is the rotational viscous damping and kt is the rotational stiffness of the door hinge. Assume that the door is 0.8 m wide (L = 0.8 m) and has a mass m of 15 kg. The moment of inertia...
