An object like a bungee jumper can be projected upward at a specified velocity. if it is subject to linear drag, its altitude as a function of time can be computed as z=z0+mc(v0+mgc)(1−e−(c/m)t)−mgct where g = 9.81 m/s2, z0 = 100 m, v0 = 55 m/s, m = 80 kg, and c = 8 kg/s. determine the time and magnitude of the peak elevation using the m-file. (round the final answers to four decimal places.)
