You are asked to design a space telescope for earth orbit. When Jupiter is 5.93 x 108 km away (its closest approach to Earth), the telescope is to resolve, by Rayleigh’s criterion, features on Jupiter that are 125 km apart. Assuming an observation wavelength of 525 nm, what minimum diameter (units: m) mirror is required?

A traveler pulls on the strap of a suitcase with 20 kg. He exerts on the suitcase a force of 30 N at an angle of 30° above the horizontal. If he pulls it a distance of 2 m, how much work does he do? What is the work done by a friction? The rolling friction between the suitcase wheels and the surface is 0.08.
