Okay, what have you done on this? Can you write the equation for this motion?
I'm confussed to the workout of this problem.
Given a mass of 2kg, stretches a spring .392m (m i believe here is meters). At all times the damping device gives a resisting force whose magnitude in Newtons is twenty times the magnitude of the velocity in m/s. The mass is released from the equilibrium position with an upwards velocity of 5m/s. How far from the equilibrium position does the object get.
They tell you that the damping force is "twenty times the magnitude of the velocity in m/s," which means that the value of 'b' is -20 N/(m/s). Also note that the signs of both the 'b' and the 'k' coefficients is negative (force of the spring is in a direction opposite to its displacement, and force of the damper is in a direction opposite its velocity).
