A spring with a 5-kg mass and a damping constant 15 can be held stretched 2 meters beyond its natural length by a force of 8 newtons. Suppose the spring is stretched 4 meters beyond its natural length and then released with zero velocity. In the notation of the text, what is the value c² - 4mk? 145 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 c₁eat + c₂eßt where α = (-15+sqrt145)/10 (the larger of the two) B= (-15-sqrt145)/10 (the smaller of the two) C1 = 15(sqrt145)+145 C₂ -143+15(sqrt145)
