A spring is fixed vertically to the floor.A 10.0-kg box is then pressed down such that the spring is compressed 0.5 m beyond its equilibrium length.The box is then released and it travels vertically upward to a maximum height of 2.40 m above its release point.Assuming the work done against drag (air resistance)is 120 J,what is the spring constant of the spring?
