If the initial velocity is zero, the downward velocity of the free-falling bungee jumper can be predicted with the following analytical solution: v=gmcd−−−√tanh(gcdm−−−√t) suppose that g = 9.81 m/s2, and m = 68.1 kg, but cd is not known precisely. for example, you might know that it varies uniformly between 0.225 and 0.275 (i. e., ±10% around a mean value of 0.25 kg/m). use the rand function to generate 1000 random uniformly distributed values of cd and then employ these values along with the analytical solution to compute the resulting distribution of velocities at t = 4 s. vary the mass uniformly by ±10%.
find out arithmetic mean, median, mode, minimum, maximum, variance (62) and standard deviation (o) of column vector v. also, draw histogram of velocity of uniform distribution.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
