1. The problem statement, all variables and given/known data A very silly person, intent on catching pigeons on the roof of an apartment building, trips and falls a distance of 44.6 m. She lands on a metal garbage can, crushing it to a depth of 0.422 m and walks away without having been seriously hurt. What acceleration did she experience during the collision? 2. Relevant equations (see solution attempt) and d=v1t+1/2at2 3. The attempt at a solution This is what I have so far for the first part of the problem (her acceleration, velocity, and position when she is free falling for 44.6m): a=-9.81 v=-9.81t d=-4.905t2+44.6 But I'm not sure how to factor in the acceleration of her crushing the garbage can... Any help would be awesome!
