A student struggled with his first midterm exam and is slightly angry. For this reason he drops a 10 kg object on the good teacher from a height of 5 m. When seeing the object fall to the ground, the teacher asks the logical question: How much will the internal energy of the box have increased after hitting the ground? If the specific heat of the box is cp = 3 kJ / kg.K How much will the temperature of the box have
