Apply conservation of energy to the system that includes both blocks. During the 0.200 m downward displacement, what is the total work done on the system by the tension in the rope? What is the change in gravitational potential energy associated with the system? Use energy conservation to find the speed of the 8.00 kg block after it has descended 0.200 m.

Answer:
A calorimeter of mass 60g contains 180g of water at 29°C . Find the final temperature of the mixture when 37.2g of ice at -10°C is added to it( specific heat capacity of water=4200J/kg/k, latent heat of ice=336×10^3 J/kg, specific heat capacity of ice=2100J/kg/k, specific heat capacity of the calorimeter is 0.42J/g/°C
