Q45 Mashed potatoes for dinner After a rough week of midterms you are eating one kg of mashed potatoes for dinner. The microwave is broken. How hard (i.e. with what speed) do you need to throw the potatoes at the floor to heat them up by 40 degrees celsius? Assume the specific heat capacity of potatoes is 0.82 kcal/kgC and thermal energy is distributed evenly through the potatoes. How would this change if you instead throw the mashed potatoes horizontally at an unbreakable bowl of mass 2kg? (Assume totally inelastic collision and all thermal energy goes to the potatoes)
