Help ASAP pleaseeee

(20 pts) After learning about special relativity, three farmers decide to see if they can fit a plane inside a barn that's normally too small for it. They plan to have a plane, which is longer than the barn, fly at extremely high speeds towards the barn. As the plane speeds up and enters the barn, it seems to fit inside. When the entire plane is inside, the farmers quickly shut both the front and back doors of the barn simultaneously at points B and C, temporarily fitting the plane inside. Then, they quickly open the doors, and the plane exits the back of the barn. Observer at Rest Front door of barn Doors close ....................
