comment Do you feel more impact force when falling straight down or tipping over?
I have unchecked the answer, out of respect for your confidence, but I am still unconvinced. John Rennie does not account for rotation. I'll have to think about whether that's okay...

For clarification, if you consider the rotational force of the fall as well as the linear force of the fall, and assumed that Δt was the same for rotational force, then would the total impact come out the same?

Thank you; I believe that you're right that the mass of the ladder will add to the impact, but the question said "Neglecting the mass of the ladder and air resistance", and I think what Prahar said about rotation is correct.

I think this is the answer I was looking for (I'll double check with dad & g-pa before I confirm it), and though I had to do a bit of work to follow your answer, I think it made sense. It somehow didn't occur to me to factor in rotational energy.

I think so. Both answers make sense in their own circumstances, but one of them factors in the mass of the ladder, something we were explicitly leaving out.
