Answer:
The force that acts on the man equals 15354.75 newtons.
Explanation:
After falling through a distance of 24.0 meters the speed of the stunt man upon hitting the mattress can be obtained using third equation of kinematics as
( u=0 since the man falls from rest)
Now since the man is decelerated through a distance of 1.15 meters thus the acceleration produced can be obtained from third equation of kinematics as
Now by newton's second law the force that produced deceleration of the calculated magnitude is obtained as
The negative sign indicates that the direction of force is opposite of motion.
