A ladder 10 meters long is leaning against the wall of a house. The base of the ladder is pulled away from the wall at a rate of meter per second. 10.m (a) What is the velocity of the top of the ladder when the base is given below? (Round your answers to three decimal places.) 2 meters away from the wall m/sec 6 meters away from the wall m/sec 8 meters away from the wall m/sec (b) Consider the triangle formed by the side of the house, ladder, and the ground. Find the rate at which the area of the triangle is changing when the base of the ladder is 6 meters from the wall. m²/sec (c) Find the rate at which the angle between the ladder and the wall of the house is changing when the base of the ladder is 6 meters from the wall. rad/sec
