Consider a spring with a 48lb weight attached that stretches 6 inches, that is initially released from 3 inches below equilibrium with velocittyy 4ft//ss in a vacuum, the spring has an external constant force of 50 lbs after 2 seconds. (Transform inches to feet)
Calculate amplitud!!
Does the external force presence increase or decrease the amplitude of the spring's motion? How much does the motion gets shifted upward by??
