3. A camera at point C is 3m from the edge of a straight section of road as shown in the following diagram. The camera detects a car travelling along the road at t=0. It then rotates, always pointing at the car, until the car passes O, the point on the edge of the road closest to the camera Acar travels along the road at a speed of 24 ms'1 .Let the position of the car be X and let OCX=0. d 93 Find E' the rate of rotation of the camera, in radians per second, at the instant the car passes the point 0
