A block is at rest on a smooth horizontal surface. A constanthorizontal force begins to act on it and does work W such that theblock picks up a velocity of 128 m/s. Assume that this work W isentirely converted to heat and given to an amount of water equal tothe mass of the block. Find the subsequent rise in the temperatureof water. Specific heat capacity of water = 4096 J/Kg-C
