Question

The minimum stopping distance in feet (tires are on the verge of skidding) for an automobi traveling at a speed of vo in mph is given by the formula: Stopping Distance) s -(0.0334 * Vo2)/f Where f is the coefficient of static friction between the tires and the road. a.) Create an anonymous function for the stopping distance of the car. The input variables should be the speed of the car "vo" and the coefficient of static friction "f b.) Plot the stopping distance of the automobile "s" for speeds ranging from 0 to 100 mph. Create this plot for f = 0.5, 0.6, and 0.2 5. The term "wind chill" was first used in 1939. During the 1940s, experiments were conducted regarding the time needed to freeze water in a plastic cylinder that was exposed to the elements They found that the time depended on how warm the water was, the outside temperature and the wind speed. The original formulas used to calculate wind chill were based on those experiments. In the fall of 2001, the U.S. National Weather Service and the Canadian weather service replaced the original formula with a new formula, which is based on greater scientific knowledge and on experiments that tested how fast the faces of volunteers cooled in a wind tunnel with various combinations of wind and temperature. The two versions of the equation are shown below, where T is the air temperature in °F and V is the wind speed in mph WCold := 0.0817(3.71w +5.81-0.25V)(T-91.4) + 91.4 WCnew = 35.74 + 0.62 15T-3575V0.16 + 0.4275TV0.16 a. Create an anonymous function for WCoia and an anonymous function for WC b. Using these functions create a table (matrix) called "results 30", where the first column is ind speed from O to 100 mph in increments of 1 mph, the 2nd column is wind chill based on the old equation, and the 3rd column is the wind chill based on the new equation -when the air temperature is 30°F Create a 2nd table (matrix) called "results 0", where everything is the same as part b, except now the air temperature is 0° F d. Plot the table created in part b and the table created in part c "side by side" in the same window. Note: The table from part b should be plotted using two curves in the same plot window (WCold vs. V) and (WCnew vs. V) for T 30 OF. Similarly, the table from part c should be plotted using two curves in the same plot window (WCold vs. V) and (WCnew vs. V) for T 0 . Use appropriate axis labels and titles for the plots.

Explanation / Answer

According to chegg policy I will answer only the first question here.Please ask the 2nd question separately.You can ask only 1 question at a time

distance_s = @(v,f) (0.0334*v*v/f);

f = 0.5; ! change the value of f here

v = zeros(101,1);

s = zeros(101,1):

for i=0:1:100

v(i+1) = i;

end

for j=0:1:100

s(i+1) = distance_s(v(j+1),f);

end

plot(v,s);
