Two friends are carrying a crate of mass 200 kg up a flight of stairs. The crate has length 1.25 m and height 0.500 m, and its center of gravity is at its center. The stairs make a 45? angle with respect to the floor. The crate also is carried at an angle 45?, so that its bottom side is parallel to the slope of the stairs. The force each person applies is vertical.

A) What is the magnitude of the upper person's force?
B) What is the magnitude of the force applied by the bottom person?
C) Is it best to be the person above or below on the stairs?
