An object is tracked by a radar station and found to have a position vector given by r = (4570-160 t) i + 2930j + 130k , with r in meters and t in seconds. the radar station's x axis points east, its y axis north, and its z axis vertically up. if the object is a 300 kg meteorological missile, what are (a) its linear momentum (in unit vector notation) and (b) the magnitude of the net force on it?

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 1.90
