The initial temperature of a lead bullet (specific heat 0.02 cal cdot g^(-1) cdot^(@)C^(-1)) of mass 50 g is 30^(@)C . It is projected upwards with a velocity of 840 m cdot s^(-1) . When the bullet falls down to the point of projection, it hits a block of ice. If the temperature of the ice will be transformed into water? Assume that the entire energy is consumed by the ice. The latent heat of fusion of ice = 80 cal cdot g^(-1) .
