1. The problem statement, all variables and given/known data The walls of an ancient shringe are perpendicular to the four cardinal compass directions. On the first day of spring, light from the rising sun enters a rectangular windows in the eastern wall. The light traverses 2.37m horizontally to shine perpendicularly on the wall opposite the window. A tourist observes the patch of light moving across this western wall. Part A: The speed the illuminated rectangle move is 1.7×10^(-4)m/s Part B: The tourist holds a small, square mirror flat against the western wall at one corner of the rectangle of light. The mirror reflects light back to a spot on the eastern wall close beside the window. The speed of the smaller square of light moves across the wall at 3.45×10^(-4)m/s Part C: In what direction does this smaller square of light on the eastern wall move. 2. Relevant equations v(1)=rω v(R)=2V(1) 3. The attempt at a solution I was able to do the part A and part b when I got to part c I said 15 degrees upward but I was told I need to put more information so I am not sure about this answer.
