A door hinged on the right is shown in the diagram below: The door is 0.8m wide and 2.2m tall. 1. Now calculate the torque applied to the door with your force as drawn. 2. If friction is negligible, calculate the angular acceleration of the door. 3. Explain how the acceleration would change if the door was not made of solid wood but rather was hollow with thin wood on the faces in a heavy steel frame. (You may assume that the mass and dimensions of the solid wood door are equal to that of the hollow door.) Do not do any calculations; just explain your reasoning.

Question
A door hinged on the right is shown in the diagram below: The door is 0.8m wide and 2.2m tall.
1. Now calculate the torque applied to the door with your force as drawn.
2. If friction is negligible, calculate the angular acceleration of the door.
3. Explain how the acceleration would change if the door was not made of solid wood but rather was hollow with thin wood on the faces in a heavy steel frame. (You may assume that the mass and dimensions of the solid wood door are equal to that of the hollow door.) Do not do any calculations; just explain your reasoning.
