Chapter 2, Problem 62GP(choose chapter or problem)
A person jumps out a fourth-story window 18.0 m above a firefighter’s safety net. The survivor stretches the net 1.0 m before coming to rest, Fig. 2–45. () What was the average deceleration experienced by the survivor when she was slowed to rest by the net? () What would you do to make it “safer” (that is, to generate a smaller deceleration): would you stiffen or loosen the net? Explain.

ANSWER:
Step 1 of 4
A person jumps from top of a building towards a safety net which is 
Assuming the initial velocity to be zero, we will find the velocity with which the person touches the safety net.
This velocity will be the new initial velocity for the stretching part.
