QUESTION ONE
When an aircraft attempts to climb as rapidly as possible, its climb rate decreases with altitude. (This occurs because the air is less dense at higher altitudes.) The table below shows performance data for a single-engine aircraft. Altitude (1000 ft) 0 2 3 4 5 Climb rate (ft/min) 925 875 830 780 730 685 Altitude (1000 ft) 6 7 8 9 10 Climb rate (ft/min) 635 585 535 490 440 (a) Calculate upper and lower estimates for the time required for this aircraft to climb from sea level to 10,000 ft. Round your answers to two decimal places. Upper estimate i minutes Lower estimate minutes{In} If climb rate data were available in increments of 250 ft, what would be the difference between a lower and upper estimate of climb time based on 40 subdivisions? Round your answer to two decimal places. The difference in estimates is n minutes. eTextbook and Media A bicyclist is pedaling along a straight road for one hour with a velocity v shown in the figure below. (km/hr) 10 20 30 40 50 60 ((minutes) She starts out seven kilometers from the lake and positive velocities take her toward the lake. Note: the vertical lines on the graph are at 10-minute (1/6-hour) intervals. Assume there are 2.5 boxes under the graph between t = 0 and t = 20 and 13 boxes under the graph between t = 20 and t = 60. (a) Does the cyclist ever turn around? If so, at what time(s)? If she never turns around, input "x". If she turns around multiple times, input the earliest time. (b) When is she going the fastest? t= minutes How fast is she going?How fast is she going? V : i km/hr Toward the lake or away? (c) When is she closest to the lake? minutes Approximately how close to the lake does she get? Round to the nearest integer. km (d) When is she farthest from the lake? t = minutes Approximately how far from the lake is she then? Round to the nearest integer.[d] When is she farthest from the lake? = n minutes Approximately how far from the lake is she then? Round to the nearest integer. n m [e] What is the total distance she traveled? Reund tn the nearest integer. n m Two cars travel in the same direction along a straight road. The figure below shows the velocity, v, of each car at time t. Car B starts 3 hours after car A and car Breaches a maximum velocity of 42 km/hr. v (km/hr) Car A Car B t (hr) (a) For approximately how long does each car travel? Car A travels for hours. Car B travels for i hours. (b) Estimate car A's maximum velocity. km/hr(b) Estimate car A's maximum velocity. km/hr (c) Approximately how far does each car travel? Car A travels km. Car B travels HI km.A car moving with velocity v has a stopping distance proportional to v2. If a car going 20 mi/hr has a stopping distance of 70 feet, what is its stopping distance going 40 mi/hr? i ft.A woman drives 10 miles, accelerating uniformly from rest to 60mph. Graph her velocity versus time. How long does it take for her to reach 60 mph? NOTE: Select the correct graph using the checkboxes. The graph will appear or change when a selection is made. velocity (mph) 60 Graph 1 Graph 2 Graph 3 Graph 4 time (hr) How long will it take her to reach 60mph? NOTE: Give your answer in minutes. She reaches 60mph after minutesStep by Step Solution
