A mass weighing 4 N is attached to a spring whose constant is 2 N/m. The medium offers a damping force that is numerically equal to the instantaneous velocity. The mass is initially released from a point 1 m above the equilibrium position with a downward velocity of 6 m/s. Determine the time at which the mass passes through the equilibrium position. (Use

g = 9.8 m/s2

for the acceleration due to gravity.)
