A plane mirror is placed along the y-axis such that x-axis is normal to the plane of the mirror. The reflecting surface of the mirror is towards negative x-axis. The mirror moves in positive x-direction with uniform speed of 5 m/s and a point object P is moving with constant speed 3m/s in negative x-direction. find the speed of image with respect to mirror in m/s.
