A 20.0-kg uniform door has a width of 1.20 m and a height of 2.50 m. The door is mounted on a post by a pair of hinges, marked 1 and 2 in the figure, at the topand bottom of the door. An external force of 60.0 N, at an angle of 30.0° above the horizontal, is applied to the small doorknob, as shown in the figure. Thedoorknob is 1.00 m above the bottom of the door.(b) Find the SUM...

A solid wood door 1.00 m wide and 2.00 m high is hinged along one side and has a total mass of 41.0 kg . Initially open and at rest, the door is struck at its center by a handful of sticky mud with mass 0.700 kg , traveling perpendicular to the door at 14.0 m/s just before impact. Find the final angular speed of the door.

A student opens a 12.0 kg door by applying a constant force of 40.0 N at a perpendicular distance of 0.900 m from the hinges. If the door is 2.00 m in height and 1.00 m wide, what is the magnitude of the angular acceleration of the door? (Assume that the door rotates freely on its hinges.) The moment of inertia for a door about the hinge is I = -mr2.
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...

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...
