A door weighing 302.0 N measures 2.00 m x 3.00 m and is of uniform density; that is, the mass is uniformly distributed throughout the volume. A doorknob is attached to the door as shown. Where is the center of gravity as measured from the center of the door if the doorknob weighs 8.30 N and is located 0.250 m from the edge? Enter a negative value if the center of gravity is toward the doorknob and enter a positive value if the center of gravity is away from the doorknob. 2.00 m 0.250 m- 3.00 m PN ON where P = 8.30 and Q = 302.0. cm
