The resolution of a telescope is ultimately limited by the diameter of its objective lens or mirror. An amateur astronomer's telescope has a 5.2 in. diameter mirror. (Take lambda to be 550 nm, near the center of the visible spectrum.)
(a) What is the minimum angular separation (in arc seconds) of two stars that can be resolved with the 5.2 in. scope?
(b) What is the minimum distance (in km) between two points on the Moon's surface that can be resolved by the 5.2 in. scope? (Note: The average distance from Earth to the Moon is 384,400 km.)
A two-stage rocket accelerates from rest at +3.27 m/s^2 for 6.82seconds. It then accelerates at +2.98 m/s^2 for another 5.90seconds. After the second stage, it enters into a state of freefall.
