Ross and Chandler are carrying a 150 kg crate up a flight of stairs. The crate is 2.0 m long and 1.5 m high, and its center of gravity is at its center. The stairs make a 45.0° angle with respect to the floor. The crate also is carried at an 45.0° angle, so that its bottom side is parallel to the slope of the stairs. If the force each person applies is vertical, what is the magnitude of each of these forces
