A 5-kg iron block released from a height of 200 m, reaches the ground at a speed of 30 m/s. What is the temperature of the block just before it strikes the ground, if its initial temperature is 10°C? Assume all thermal energy produced by friction is absorbed by the block. (Take Ciron n= 450 J/kg°C) %3D
