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.

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.
Answer:
II) Kitchen waste: Meal leftovers, Banna peelings
Garden Waste: Camote leaves, Kangkong leaves, weeds
Factory: Glass bottles, carton pieces
III) A
IV) Home: Bottles of shampoo, leftover food, syringe
office Gloves
Classroom: containers
Laboratory: empty cartridge
It is wasted, most likely as light, in this case, or it is lost during the transport of electricity.
To solve this problem it is necessary to apply the kinematic equations of motion.
By definition we know that the position of a body is given by

Where
Initial position
Initial velocity
a = Acceleration
t= time
And the velocity can be expressed as,

Where,

For our case we have that there is neither initial position nor initial velocity, then

With our values we have
, rearranging to find a,



Therefore the final velocity would be



Therefore the final velocity is 81.14m/s
