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.

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
