May I ask how to solve a problem that states the following? "In the preceding problem, suppose that the copper block is dropped into the water from a height of 50m. Assuming no loss of water from the tank, what is the change in internal energy of the block? These are what have been given from a previous problem that connect to this one: - m_block = 0.2 kg, C_v,block = 0.380 J/g*K, T_block = 400 K (initially) - C_v,water = 4.184 J/g*K, m_water = 4 kg, T_water = 300 K (initially) - m_Tank = 0.5 kg - Tank is made of copper and is perfectly insulated I tried solving this but could not get to the right answer because of being unsure of what to use and how to use it. I would greatly appreciate your help.

If a hot substance is in contact with a cold substance, the heat is transferred from the hot substance to the cold substance. The transfer of heat continues until the substances maintain a thermal equilibrium.
In the problem, the equilibrium temperature is to be calculated and from this equilibrium temperature the change in internal energy is to be calculated.
