Q1. Assume that you are walking perpendicularly with a velocity of +0.90 m/s toward a stationary plane mirror. What is the velocity of the image relative to you? The direction in which you walk is positive direction.

Q2. Two stars are 3.3 x 1011 m apart and are equally distant from the earth. A telescope has an objective lens with a diameter of 1.00 m and just detects these stars as separate objects. Assume that light of wavelength 550 nm is being observed. Also suppose that diffraction effects, rather than atmospheric turbulence, limit the resolving power of the telescope. Find the greatest distance that these stars might be from the earth.
