The height h in feet of an object that is dropped from a height of a feet is given by the formula h= s -16t2 , where t is the time the object has been falling. A 5-foot-tall woman on a sidewalk looks directly overhead and sees a windows washer drop a bottle from 5 stories up. How long does she have to get out of the way? Round to the nearest tenth. A story is 12 feet.

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

v(t)A 7 0 1 2 3 45 6 1 Time (in hours) A particle starts out from the origin. Its velocity, in miles per hour, is given by: v(t) = Vi +t, where t is the number of hours since the particle left the origin. How far does the parti- cle travel during the second, third, and fourth hours (from t = 1 to t = 4)? Velocity (in miles per hour)

In astronomy, a unit of distance is used called the Astronomical Unit. It is the average distance from the Earth to the Sun. If 1 au is 1.49 × 1011 m, and a light-year is the distance it takes light to travel in 1 year elapsed time (light travels at a speed of c = 3.0 x 108 ), then how many au is it to get to Alpha Centauri (our closest star with a planetary system) if is 4.367 lightyears away?

Police use the formula: v = V20L to estimate the speed of a car, v, in miles per hour, based on the length, L, in feet, of its skid marks when suddenly braking on a dry, asphalt road. At the scene of an accident, a police officer measures a car's skid marks to be 158 feet long. Approximately how fast was the car traveling? Round your answer to the nearest tenth (one decimal place) of a unit. Answer: The car was traveling at approximately miles per hour.
