Mmm tricky.
Constant velocity means there's no net force acting on the puck!

So if there's no friction or air drag force to slow it down, you don't need any force to keep that puck moving.

Once it's in motion, it stays in motion.
(Mmm isn't that a Law of Newton?)
:D

A stunt man jumps from the top of a building and lands 10 meters below his initial height. In case A, the stunt man lands on a s
krek1111 [17]

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.

Impulse=F_{avg}\times \Delta T

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.
