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.)

10 newton object is placed 3 meters from the fulcrum. at what distance on the other side would you need to place a 15 newton object to balance the lever? show your work!

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)

Thermal radiation gets its name because
