Q. Convex mirrors are commonly used as rear-view mirrors in vehicles. Suppose you are sitting in a parked car, you notice a jogger approaching towards you in the side view rnirror.The radius of Curvatureof the side view mirror is 2cm, lf the jogger is running at a speed of 5m/s,how fast the image of the jogger appears to move when the jogger is 9m away from the mirror?
