Hi this is a problem from my midterm at the beginning of the quarter and i have a final coming up so i need to know the previous midterm material but i still dont understand this one question.(adsbygoogle = window.adsbygoogle || []).push({});

Dave suddenly drops from the wire and lands at a velocity of 2m/s on some cardboard boxes that contract to absorb the force of his fall. If the cardboard boxes exerts a force of 350N on Dave who weighs 70kg, how much do the cardboard boxes contract?

the equation i would use is v^2=vo^2 - 2adelta y

but in her solutions she shoes delta x. Why is it delta x if the cardboard is going to be contracting in the y direction?

If someone can help me start off this problem i will so grateful!
