(10 points) a spring with a 7-kg mass and a damping constant 12 can be held stretched 1 meters beyond its natural length by a force of 4 newtons. suppose the spring is stretched 2 meters beyond its natural length and then released with zero velocity. in the notation of the text, what is the value c2?4mk? m2kg2/sec2 find the position of the mass, in meters, after t seconds. your answer should be a function of the variable t of the form c1e?t+c2e?t where ?= (the larger of the two) ?=
