How do i Solve this physics Problem?
A person jumps from a forth story window 15.0m above a safety net. the survivor stretches the net 1.0m before coming to rest.
a) what was the average deceleration expericened by the survivor when she was slowed to rest by the net?
Velocity just before reaching the net:
v² - (vo)² = 2gx
v² = 2(9.81 m/s²)(15.0 m)
v = 17.16 m/s
Net decelerating the person:
v² - (vo)² = 2ax
0 - (17.16 m/s)² = 2a(1.0 m)
a = -147 m/s²
