A laser pointer is placed on a platform that rotates at a rate of 16 revolutions per minute. The beam hits a wall 8 m away, producing a dot of light that moves horizontally along the wall. Let 0 be the angle between the beam and the line through the searchlight perpendicular to the wall. How fast is this dot moving when 0 = - Wall 8 m Laser (Use decimal notation. Give your answer to one decimal place.) velocity of the dot: m/min
