You're going to open the door further by giving it a brief, hard push. first, you'll push the door at its center. then, you'll push it near the door knob. both pushes are equally hard, and last the same length of time. and in both cases you direct your push perpendicular to the plane of the door. (a)which push will give the door more rotational motion?

Two children on opposite sides of a 13 kg door (i = 1/3 ml 2 ) apply a force to the door. the first child pushes with force f at an angle of 80° relative to the door at a position r 1 from the door’s hinges. the second child pushes with a force of 15 n perpendicular to the door at a position 0.3 m from the door’s hinges. the width of the door is 0.4 m. what is the door’s angular acceleration?
