Question

A metal block of density 6000 kg m-3 and mass 1.2 kg
is suspended through a spring of spring constant
200 Nm-1 The spring-block system is dipped in water
kept in a vessel. The water has a mass of 260 g and the
block is at a height 40 cm above the bottom of the vessel.
If the support to the spring is broken, what will be the
rise in the temperature of the water. Specific heat
capacity of the block is 250 J kg-1 K-1 and that of water
is 4200 J kg-1 K-1 Heat capacities of the vessel and the
spring are negligible.​
