1. A person opens a 7.25 kg door by applying a force of 125 N perpendicular to it at a point 0.85 m from the hinges. The door measures 2.25 m high and 1.15 m wide. Find the angular acceleration of the door. If the door is pushed wide open by 75.0° in 2.0 s, find the work done on the door and the power delivered to the door
