Don’t forget, the chicken is frozen, so you also have to take into account the latent heat of fusion to melt the chicken before you can raise the temperature
This calculation also assumes that this is an inelastic collision where all the energy is absorbed into the chicken and not into your hand or into the air as sound or other kinetic energy.
Further the chicken is frozen solid, and, presumably, your hand is not. Of the two objects in this collision that could deform inelasticity and absorb the larger fraction of the energy, my money would be on the 0.4 kg slab of raw meat rather than the 1kg frozen billiard ball.
One must also consider the thermal conduction of the chicken. Slapping it, either once or multiple times, on a single area will impart energy to that area, raising the temperature there, but it will take time for that to disperse throughout the fowl. Thus will inevitably lead to the slapped area/areas being overcooked and the rest being dangerously undercooked. Losses to the environment must additionally be taken into account unless sufficient insulation is employed to mitigate this.
Since we're being pedantic, the feeezing point of unbrined chicken is -3 C. Most meats are not frozen at exactly 0 C since the water contained in the cells is far from pure.
But yeah, slapping will be a super lossy process and this analysis will be off by quite a bit.
Touché!
I wonder if there’d be any fractional freezing at 0C 🤔
Great… now I’m imagining raw chichen slushie 🤮
Isn't 1600 m/s greater than the speed of sound? That sonic boom is gonna mess up the kitchen, if not the hand.
