A beetle and a spider are sitting on a hinged door. The beetle is in the middle of the door and the spider is near the handle, making its position twice as far from the hinge as the beetle. When the door is opened with a constant angular speed what is the angular speed and tangantial Speed of the spider compared to the beetle? Please explain answer
