Similar to the previous problem, we heat about a cup (230 g) of milk (we'll treat it like water, with a specific heat of 4186 J/kg °C) from refrigerator temperature (5.2 °C) to a comfortable drinking temperature (52.5 °C) in order to make a cup of hot chocolate. First, find the energy required to heat this milk. Next, imagine giving a 1,600 kg truck this same amount of kinetic energy. What speed (in m/s) will the truck be travelling?
