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.

Calculate the horizontal force P required to push the 85-lb lawn mower at constant speed. The center of gravity of the mower is at G, and the coefficients of rolling resistance are 0.12 for the front wheels and 0.18 for the rear wheels.
A machine part has the shape of a solid uniform sphere of mass 220 gg and diameter 3.50 cmcm . It is spinning about a frictionless axle through its center, but at a point at the top of the sphere, it is scraping against metal, resulting in a friction force of 0.0200 NN at that point. Find the angular acceleration of the sphere, including the direction (a positive value would indicate the +z direction and a negative value would indicate the -z direction).

The inner and outer radii of a hollow steel shaft are 50 mm and 100 mm, respectively. The hub of a steel gear wheel that is shrunk onto the hollow shaft has an outer radius of 150 mm.
