Question
![|An 80 kg movie actor is preparing for a stunt in which she will fall
from a window a height h above a safety net. The safety net can be considered as an ideal
spring with a spring constant 2000 N/m. The actor will fall from rest from the window
and land in the net. The net will then sink down to a final height yf. (The net will then
spring back and launch her back into the air, but you should ignore that.) Take the origin
to be at the original height of the safety net, which is also the relaxed position of the net.
