Write a function convstrs that will receive a char matrix of characters and a character ‘u’ or ‘l’. if the character is ‘u’, it will return a new char matrix with all of the characters in uppercase. if the character is ‘l’, it will return a new char matrix with all of the characters in lowercase. if the character is neither ‘u’ nor ‘l’, the char matrix that is returned will be identical to the input char matrix.

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.
