Asmall mirror is attached to a vertical wall, and it hangs a distance of 1.70 m above the floor. the mirror is facing due east, and a ray of sunlight strikes the mirror early in the morning and then again later in the morning. the incident and reflected rays both lie in a plane that is perpendicular to both the wall and the floor. early in the morning, the ray is observed to strike the floor at a distance of 3.75 m from the base of the wall. later on in the morning, the ray strikes the floor at a distance of 1.18 m from the wall. the earth rotates at 15.0 degrees per hour. how much time (in hours) has elapsed between the two observations
