you have done it absolutely correct. No mistakes.
I suggest dont give answer in only one significant figure unless asked in the question.
Does this working look correct What is the total stopping distance ? Xr + XB =...
A statistical program is recommended The following observations are on stopping distance (ft) of a particular truck at 20 mph under specified experimental conditions 32.1 30.7 31.4 30.4 31.0 31.9 The report states that under these conditions, the maximum allowable stopping distance is 30. A normal probability plot validates the assumption that stopping distance is normally distributed (a) Does the data suggest that true average stopping distance exceeds this maximum value? Test the appropriate hypotheses using α = 0.01 State...
Stopping sight distance (SSD) is defined as the distance needed for a driver to see an object on the roadway and then stop before colliding with it. It's composed of the distance to react on first seeing the object and then the distance to stop after the brake is engaged. The following is a formula for determining stopping sight distance: ssi) = (. | c:/ + |-. SSD is the stopping sight distance (m or ft e is the conversion...
You're working for Ford as a safety engineer. You job is to check the stopping ability of different types of brakes. To do this, you measure the stopping distance of cars in order to determine their acceleration. If a car moving at an initial velocity of 25.6 m/sec has a stopping distance of 99.6 meters, what is the magnitude of it's acceleration? Give you answer in units of m/s2 to at least three significant figures to avoid being counted off...
Please help me get the right values, I cannot figure it out. Please show your work. A statistical program is recommended The following observations are on stopping distance (ft) of a particular truck at 20 mph under specified experimental conditions 32.1 30.8 31.7 30.4 31.0 31.9 The report states that under these conditions, the maximum alowable stopping distance is 30. A normal probability plot validates the assumption that stopping distance is normally distributecd. (a) Does the data suggest that true...
The total stopping distance Tof a vehicle is T- 6.x+1.5x where T is in feet and x is the speed in miles per hour. Use differentials to approximate the percent change in total stopping distance as speed changes from x-22 to x = 27 miles per hour. Round your answer to one decimal place. 15. a. 41.7% b. 80.0% c. 21.9% d. 122.7% e. 50.3% The total stopping distance Tof a vehicle is T- 6.x+1.5x where T is in feet...
In a test of braking performance, a tire manufacturer measured the stopping distance for one of its tire models. On a test track, 10 different cars made repeated stops from 60 miles per hour. The test was run on both dry and wet pavement, with the accompanying results. Complete parts a) and b) below. EClick the icon to view the table of stopping distances. a) Construct a 95% confidence interval for the mean dry pavement stopping distance. Be sure to...
Please help and thank you! Determine the required stopping sight distance. 18. A vehicle is travelling with a speed of 40 mph over an equal tangent vertical curve which has an initial grade of +4.0% and final grade of-2.000. If the height of the driver's eye if 6.0 ft and the driver spots a car 460 ft away with a height of 4.0 ft, what is the minimum length of the vertical curve for this situation?
What percentage of the variation in the observed stopping distances is explained by a linear relationship between speed and stopping distance? Group of answer choices 98.5% 16.1% 96.7% 65.9% 96.9% A study was conducted on stopping distances in feet for a car tested 3 times at each of 5 speeds to see whether or not there is a relationship between stopping distance and speed. Use the Excel regression output shown here to answer questions 14 through 30. Stopping Distance vs...

Does this look correct, also what protons would have the most downfield shift
