Emilie wishes to fly to Phun City, a place where Physics Geeksrule the land, loacted 800 km [N] of her present postion. Her planeis capable of an air velocity of 300km/hr. There is a wind blowing120 km/hr [S 40 (degrees) W]
a) If she flies directly at Phun City, what will be her observedground velocity?
b) to arrive at Phun City, what should her original heading havebeen?
c) what will her flight time to Phun City be?
The intensity of radiation from a distant source like the Sunvaries inversely with the square of the distance from thesource. At the top of Earth's atmosphere the solar intensity(power per unit area) is 1.35 kW/m2.
