Answer:
The deceleration is
Explanation:
From the question we are told that
The height above firefighter safety net is
The length by which the net is stretched is
From the law of energy conservation
Where is the kinetic energy of the person before jumping which equal to zero(because to kinetic energy at maximum height )
and is the potential energy of the before jumping which is mathematically represented at
and is the kinetic energy of the person just before landing on the safety net which is mathematically represented at
and is the potential energy of the person as he lands on the safety net which has a value of zero (because it is converted to kinetic energy )
So the above equation becomes
=>
substituting values
Applying the equation o motion
Now the final velocity is zero because the person comes to rest
So
