A construction worker pulls a five-meter plank up the side of a building under construction by means of a rope tied to one end of the plank (see figure). Assume the opposite end of the plank follows a path perpendicular to the wall of the building and the worker pulls the rope at a rate of 0.19 meter per second. How fast (in m/sec) is the end of the plank sliding along the ground when it is 1.8 meters from the wall of the building? (Round your answer to two decimal places.) m/sec 5 m 2
