A group of hikers uses a GPS while doing a 40-mile trek in Colorado. A curve fit to the data shows that their altitude can be approximated by the function y(t)=0.12t5−6.75t4+135t3−1120t2+3200t+9060 where y and t are expressed in feet and hours, respectively. During the 18-hour hike, determine the maximum altitude that the hikers reach.

The speed of light is c = 3.0 x 10^8 m/s. If the distance between the Earth and the moon is d = 2.39 x 10^5 mi (1.0 mi = 1.61 km). You send a laser from the Earth to the moon and back. How long does this take?
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.)
true or false. I- The speed of light in vacuum is a universal constant, whose value (without uncertainty, as it is defined as a standard) is c=299792458 m.s -1..The value of c in scientific notation is 2.99792458 x108 m.s-1. II- The value of c (velocity of light in vacuum) written to 3 significant figures is 3.00 x 108 .m.s-1. III- The value of the density of an object obtained was ρ±uρ=(7.768581114 ± 0.012540242) g.cm -3. The value obtained for the density and its respective uncertainty is incorrect, as it makes no sense to report the uncertainty with so many decimal places. IV- To convert g/cm 3 to kg/m 3 just multiply by 10 3.
