Determine the equations of motion if the following is true. (a) the mass is initially released from rest from a point 1 meter below the equilibrium position x (t ) = (b) the mass is initially released from a point 1 meter below the equilibrium position with an upward velocity of 12 m/s x (t) = m Need Help?
