A 0.50 kg mass on the end of an ideal spring (k = 60.0 N/m) is released from its equilibrium position with an initial velocity of 0.50 m/s.

What is the displacement (in meters) that the mass be from the equilibrium position at time t = 5.0 s.

Hint: don't just blindly use the formula we derived. There is one important difference here: the mass is initially shot from the equilibrium position, rather than initially released from a stretched position.
