A police cruiser hunting for a suspect pulls over and stops at a point a = 10 ft from a straight wall. The flasher on top of the cruiser revolves at a constant rate of 75°/second, and the light beam casts a spot of light as it strikes the wall. How fast is the spot of light moving along the wall at a point 50 ft from the point on the wall closest to the cruiser?
