Starting at noon, Sophie observed the amount of snow on her lawn during a blizzard. She created a graph to represent how many inches of snow were on the lawn at x
minutes past noon. What does the y-intercept in the graph represent?

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
