A ladder leaning against a wall is falling. The ladder is of length, L, and at this instant the ladder is at an angle, theta(), with respect to the wall, and the horizontal velocity of the base of the ladder ,v_A, is known. All answers are I'm the terms given , fixed coordinate system, OXYZ.( Point A is the ladder bottom, Point C is the center, and point B is the top of the ladder.(the point in contact with the wall)

1)What is the velocity, at this instant , of point C in terms of v_A, L, theta(), and g?
