Answer:
Explanation:
The stunt will likely sustain serious injury in case of concrete blocks because the average force acting on the person will be more because concrete blocks do not squeeze to provide more time for the force to act on the body instead it acts for a small amount of interval.
[tex]Impulse=F_{avg}\times \Delta T[/tex]
As impulse is constant so time requires to act force on the body is more as compared to concrete block and thus average force in mattress case is less.
The Stunt man will most likely sustain a serious Injury when he lands on a stack of concrete blocks ( Case B )
The Average force Logic
The logic behind sustaining a serious injury when the stunt man lands on a stack of blocks is that, the average force which would act on the stunt man when he lands on a stack of concrete blocks is greater than the average force that would act on the stunt man when he lands on the stack of mattresses.
Concretes do not squeeze ( constant impulse ). but mattresses squeeze therefore producing a lesser average force on the stunt man.
Hence we can conclude that The Stunt man will most likely sustain a serious Injury when he lands on a stack of concrete blocks ( Case B )
