A projectile is fired straight upward from planet's surface with a speed that is 1/7 the planet's escape speed. Let R be the radius of the planet. What is the highest distance from the center of the planet in units of R the projectile will reach? Give your answer to three significant figures.
Suppose you weigh 150 lb on Earth. If you stood on a planet having three times the mass of Earth and a radius three times as big as Earth's radius, how much would you weigh?

- How many precession periods are in one cycle of Earths axis inclination variation? In one cycle of Earths orbit eccentricity variation? In the time span shown in Figure 2-11b, how many periods or fractions of periods did the Earths axis precess, nod, and Earths orbit change shape? Of the three periods, which is likely to have the most effect on the changes shown in Figure 211?arrow_forwardStudy Figures 4-11 and 4-16 and describe the phases that Venus would have displayed to Galileos telescope if the Tychonic universe had been correct. Figure 4-11 Tychos model of the Universe retained the first principles of classical astronomy; it was geocentric with the Sun and Moon revolving around Earth, but the planets revolved around the Sun. All motion was along circular paths. Figure 4-16 (a) If Venus moved in an epicycle centered on the Earth-Sun line (see Figure 3b in the Chapter 2 Concept Art: An Ancient Model of the Universe), it would always appear as a crescent. (b) Galileo observed through his telescope that Venus goes through a full set of phases, proving that it must orbit the Sun.arrow_forwardThe acceleration due to gravity on Eartha. is the same at all locations on the surface of Earthb. is greater for heavier objectsc. is greater at the equator and less at the polesd. is the same at any two locations provided that the distance to the centre of Earth at thoselocations is the samee. varies slightly with latitudearrow_forward
