A patrol car is parked 30 feet from a long warehouse (see figure). The revolving light on top of the car turns at a rate of 34 revolutions minute. How fast is the light beam moving (in ft/sec) along the wall when the beam makes angles of 0 = 30, 0 = 60, and 0 = 75 wi the line perpendicular from the light to the wall? (a) = 30 (b) = 60 yft ft/sec ft/sec (c) = 75 (Round your answer to two decimal places.)
