A 4 kg object traveling at 60 m/s, enters an insulated vat of 20 kg of incompressible fluid (C = 2.0 kJ/kgK) and comes to rest before hitting the bottom. Neglecting potential engergy, and taking the object and liquid as a system, how much word the Temperature of the liquid rise or fall? Assume the temperature of the object doesn not change.
