The equation for the line of best fit was determined to be y=0.038sin(9.56t+0.20)−0.09, where t is time in seconds and y is displacement in meters. The team used a 1 kilogram mass which displaced the spring 0.09 meters below equilibrium. We can use their initial conditions of y(0)=−0.083 and the fact that the spring was released from rest – thus y′(0)=0. Your job is to build the equation of motion for this spring. The damping coefficient c is unknown, but can you make a decent estimate for the value of c? Please consider whether the spring should be under/over/critically damped based on what you understand of the context. This can help you determine a value, or at least a range of possible values, for c. Compare and contrast the two displacement models. What caused the differences? Which one do you think is better?
