A screen door is blowing in the wind, so you grab the edge to pull it closed. The door has width w = 1.2 m, with a moment of inertia I = 5.2 kg - m2. Your hand exerts a force Fhand = 24 N perpendicular to the edge of the door; the wind exerts a force of med = 39 N in the opposite direction at the center of the door. A. What is the angular acceleration of the screen door? B. Suppose you rotate the door through onequarter of a rotation to close it. Use the given variables (i.e., don't plug in any numbers) to nd: 1. The angular work done by your hand. 2. The rotational kinetic energy of the door at the end of its travel, assuming it starts from re st
