A 15 foot ladder is leaning against a wall. The grips on the feet of the ladder start slipping, causing the bottom to slide out along the floor, and the top of the ladder begins sliding down the wall. This causes the angle formed between the base of the ladder and the floor to decrease at a rate of 0.3 radians/sec. Jimbo is standing with his back to the wall, 12 feet away from it. He's in the path of the sliding ladder, so eventually, the FEET of the ladder will hit him in HIS feet as it slides across the floor. At the moment the ladder hits him in his feet, what is SPEED of the ladder sliding along the floor? 1.3 feet/sec 2 feet/sec 4 feet/sec 2.7 feet/sec
