5. Yvonne is pulling on the doorknob of her dorm door to keep it closed while Joyce is pulling from the other side to try to get into the room. The doorknob is 0.7 m from the hinge of the door. Yvonne is using a force of 75 N exerted at an angle of 75° to the door. What force does Joyce need to use to open the door if she is exerting force at an 85° angle to the door? (Yvonne 0.7 m 75 hinge knob' 85 V Joyce
