1. The problem statement, all variables and given/known data The sphere of lead with mass 2kg and velocity 20m/S hits a block of ice and is stuck in it. Find the mass of ice that melts during the hit. The initial temperature of the sphere is 293 K and c=128J/kg*grade. 2. Relevant equations m1v1=m2v2 3. The attempt at a solution I thought to use the formula but what is the v of ice?
