Question

You contact the jumpers used to generate the data in Table 2.1 and measure their frontal areas. The resulting values, which are ordered in the same sequence as the corresponding values in Table 2.1, are A, m2 0.455 0.402 0.452 0.486 0.531 0.475 0.487 If the air density is rho = 1.223 kg/m3, use MATLAB to compute values of the dimensionless drag coefficient CD. Determine the average, minimum and maximum of the resulting values. Develop a stacked plot of A versus m (upper) and CD versus m (lower). Include descriptive axis labels and titles on the plots.

Explanation / Answer

ata = [0.455 0.402 0.452 0.486 0.531 0.475 0.487]; %# Sample data xRange = 0:1.233; %# Range of integers to compute a probability for N = hist(data,xRange); %# Bin the data plot(xRange,N./numel(data)); %# Plot the probabilities for each integer xlabel('Integer value'); ylabel('Probability');
