The height of the haystack is 1 meter. You press down on topof the stack and discover that to compress the stack by 25cm, you have to exert a force of about 50N. Second floor is 6 metersabove the ground.
Solve the problem by breaking it into pieces:
1. What is the haystack's spring constant?
2. Is the haystack tall enough to bring your speed tozero?(Estimate using conservation of energy)
3. If you do come to a stop before you hit the ground, what willthe average force exerted on you be?
