Question:
A spring (k = 500 N/m) supports a 400-g mass, which is immersed in 900 g of water. The specific heat of the mass is 450 J/kg · K. The spring is now stretched 15 cm, and after thermal equilibrium is reached, the mass is released so it vibrates up and down. By how much has the temperature of the water changed when the vibration has stopped?
