2/3 points previcus answers zillengmaths 3.8.029 my notes ask your te a force of 8 pounds stretches a spring 1 foot. a mass weighing 3.2 pounds is attached to the spring, and the system is then immersed in a medium that offers a damping force numerically equal to 0.8 times the instantaneous velocity. (use a for the acceleration due to gravity.) (a) find the equation of motion if the mas is initially released from rest from a point foot above the equilibrium position. (b) express the equation of motion in the decimal places.) -vse "sin(st+4.25)j (c) find the first time at which the mass passes through the equilibrium position heading upward. (round your answer to three decimal places.) 0.254 ebook
