Suppose that, while lying on a beach near the equator watching the Sun set over a calm ocean, you start a stopwatch just as the top of the Sun disappears. You then stand, elevating your eyes by a height H = 1.70 m, and stop the watch when the top of the Sun again disappears. If the elapsed time is t = 11.1 s, what is the radius r of Earth?

A pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69
A communications satellite is in a circular orbit about the Earth at an altitude of 3.56 104 km. How many seconds does it take a signal from the satellite to reach a television receiving station? (Radio signals travel at the speed of light, 3.00 108 m/s.)

A circular area S is concentric with the origin, has radius a, and lies in the yz-plane. Calculate ∫??⃗·?ˆ??∫SE→·n^dA for ?⃗=3?2?ˆ.E→=3z2i^.
How long should it take the voices of astronauts on the Moon to reach the Earth? Assume that the only significant time is the transit time from the Earth to the Moon, at the speed of light. Suppose that the astronaut on the surface of the Moon, the receiver on the surface of the Earth, and the centers of the Earth and the Moon are aligned. The distance between the centers of the Earth and the Moon is 384×103km, the radius of the Earth is 6.38×103km, the radius of the Moon is 1.74×103km.
You have been hired by the defense attorney as an expert witness in a lawsuit. The plaintiff is someone who just returned from being a passenger on the first orbital space tourist flight. Based on a travel brochure offered by the space travel company, the plaintiff expected to be able to see the Great Wall of China from his orbital height of 200 km above the Earth’s surface. He was unable to do so, and is now demanding that his fare be refunded and to receive additional financial compensation to cover his great disappointment. Construct the basis for an argument for the defense that shows that his expectation of seeing the Great Wall from orbit was unreasonable. The Wall is 7 m wide at its widest point and the normal visual acuity of the human eye is 3 x 10-4 rad. (Visual acuity is the smallestsubtended angle that an object can make at the eye and still be recognized; the subtended angle in radians is the ratio of the width of an object to the distance of the object from your eyes.)
The angle between two radii of a circle with radius 1.50 m is 0.700 rad. What length of arc is intercepted on the circumference of the circle by the two radii?
. In an experiment to measure the gravitational acceleration g, the distance of fall y and the time taken were measured to be 60.0 + 0.3 cm and 0.351 + 0.001 s.Find the gravitational acceleration g and its percentage uncertainty Δg /g. The accepted value for g is 9.80 m/s2. Find the percentage error. ( ? = 1/2 ??^2)
A farmer wants to fence off his four-sided plot of flat land. He measures three sides, shown as A, B, and D in the Figure, and then correctly calculates the length and orientation of the third side C. The length of A, B, and D are all 7.06 km. Their angles theta1, theta2, and theta3 are all 2.16 degrees. What did he find as the magnitude of C (in unit of km)?
A ship is sailing due north. At a certain point, the bearing of a lighthouse 8.5km away is N^(38).5\deg E. Later on, the captain notices that the bearing of the lighthouse has become $34.2\deg E. How far did the ship travel between the two

A jetliner can fly 4.8 hours on a full load of fuel. Without any wind, it flies at a speed of 2.68 x102m/s. The plane is to make a round trip by heading due west for a certain distance, turning around, and then heading due east for the return trip. During the entire flight, however, the plane encounters a 69.9 m/s wind from the jet stream, which blows from west to east. What is the maximum distance that the plane can travel due west and just be able to return home?
