The Rock with a Changed Reference Point Make graphs of position and velocity for a rock tossed upward from ground level as it might be viewed by someone standing atop a tall building. Thus, the location of the rock is measured by its distance down from the top of the building.arrow_forwardReminder Round all answers to two decimal places unless otherwise indicated. Walking and Running You live east of campus, and you are walking from campus toward your home at a constant speed. When you get there, you rest for 5minutes and then run back west at a rapid speed. After a few minutes, you reach your destination, and then you rest for 10minutes. Measure your location as your distance west of your home, and make graphs of your location and velocity.arrow_forwardReminder Round all answers to two decimal places unless otherwise indicated.

Gravity on Earth and on MarsThe acceleration due to gravity near the surface of a planet depends on the mass of the planet; larger planets impart greater acceleration than smaller ones. Mars is much smaller than Earth. A rock is dropped from the top of a cliff on each planet. Give its location as the distance down from the top of the cliff. a.On the same coordinate axes, make a graph of distance down for each of the rocks. b.On the same coordinate axes, make a graph of velocity for each of the rocks.arrow_forwardReminder Round all answer to two decimal places unless otherwise indicated. Hair Growth When you are 18 years old you have a hair that is 14 centimeters long, and your hair grows about 12 centimeters each year. Let H(t) be the length, in centimeters, of that hair t years after age 18. a. Find a formula that gives H as a linear function of t. b. How long will it take for the hair to reach a length of 90 centimeters?arrow_forwardReminder Round all answers to two decimal places unless otherwise indicated. Looking Up The constant g32feetpersecondpersecond is the downward acceleration due to gravity near the surface of the Earth. If we stand on the surface of the Earth and locate objects using their distance up from the ground, then the positive direction is up, so down is the negative direction. With this perspective, the equation of change in velocity for a freely falling object would be expressed as dVdt=g. We measure upward velocity V in feet per second and time t in seconds. Consider a rock tossed upward from the surface of the Earth with an initial velocity of 40feetpersecond upward. a. Use a formula to express the velocity VV(t) as a linear function. Hint: You get the slope of V from the equation of change. The vertical intercept is the initial value. b. How many seconds after the toss does the rock reach the peak of its flight? Hint: What is the velocity of the rock when it reaches its peak? c. How many seconds after the toss does the rock strike the ground? Hint: How aces me time it takes for the rock to rise to its peak compare with the time it takes for it to fall hack to the ground?arrow_forward

Making Up a Story about a Car TripYou begin from home on a car trip. Initially your velocity is a small positive number. Shortly after you leave, your velocity decreases momentarily to zero. Then it increases rapidly to a large positive number and remains constant for this part of the trip. After a time, your velocity decreases to zero and then changes to a large negativc number. a. Make a graph of velocity for this trip. b. Discuss your distance from home during this driving event, and make a graph. c. Make up a driving story that matches this description.arrow_forward

In each case, assume that the car leaves from home moving west down a straight road and that position is given as the distance west from home. a. A vacation: Being eager to begin your overdue vacation, you set your cruise control and drive faster than you should to the airport. You park your car there and get on an airplane to Spain. When you fly back 2 weeks later, you are tired, and you drive back home at a leisurely pace. Note: Here we are talking about the location of your car, not of the airplane. b. On a country road: A car driving down a country road encounters a deer. The driver slams on the brakes, and the deer runs away. The journey is cautiously resumed. c. At the movies: In a movie chase scene, our hero is driving his car rapidly toward the bad guys. When the danger is spotted, he does a Hollywood 180-degree turn and speeds off in the opposite direction.arrow_forwardReminder Round all answers to two decimal places unless otherwise indicated. View from the Top Your office window is 35 feet high. Looking out your window, you find that the top of a statue lines up exactly with the bottom of a building that is 600 horizontal feet from your office. You know that the statue is 125 feet from the building. How tall is the statue? See Figure 3.14.)arrow_forwardReminder Round all answers to two decimal places unless otherwise indicated. Surveying Vertical CurvesWhen a road is being built, it usually has straight sections, all with the same grade, that must be linked to each other by curves. By this we mean curves up and down rather than side to side, which would be another matter. Its important that as the road changes from one grade to another, the rate of change of grade between the two be constant. The curve linking one grade to another grade is called a vertical curve. Surveyors mark distances by means of stations that are 100feet apart. To link a straight grade of g1 to a straight grade of g2, the elevations of the stations are given by y=g2g12Lx2+g1x+Eg1L2. Here y is the elevation of the vertical curve in feet, g1 and g2 are percents, L is the length of the vertical curve in hundreds of feet, x is the number of the station, and E is the elevation in feet of the intersection where the two grades would meet.See Figure 5.72. The station x=0 is the very beginning of the vertical curve, so the station x=0 lies where the straight section with grade g1 meets the vertical curve. The last station of the vertical curve is x=L, which lies where the vertical curve meets the straight section with grade g2. Figure 5.72 Assume that the vertical curve you want to design goes over a slight rise, joining a straight section of grade 1.35 to a straight section of grade 1.75. Assume that the length of the curve is to be 500feet so L=5 and that the elevation of the intersection is 1040.63feet. a.What is the equation for the vertical curve described above? Dont round the coefficients. b.What are the elevations of the stations for the vertical curve? c.Where is the highest point of the road on the vertical curve? Give the distance along the vertical curve and the elevation.arrow_forward
