A small mirror is attached to a vertical wall

Reference no: EM13653818

A small mirror is attached to a vertical wall, and it hangs adistance of 1.56 m above the floor. The mirror is facing due east,and a ray of sunlight strikes the mirror early in the morning andthen again later in the morning. The incident and reflected rayslie in a plane that is perpendicular to both the wall and thefloor. Early in the morning, the reflected ray strikes the floor ata distance of 3.35 m from the base of the wall. Later on in themorning, the ray is observed to strike the floor at a distance of1.27 m from the wall. The earth rotates at a rate of 15.0° perhour. How much time (in hours) has elapsed between the twoobservations?
