It’s commonly understood that “It’s not the fall that kills you, it’s the sudden stop at the end.” Afew summers ago I was roofing my house – the peak of which is roughly 18 feet above theground. Let’s say I got so caught up in the joy of shingling, I carelessly stepped off the roof,falling to the pavement. Striking the ground, if my head came to rest over a distance of 8 mm(that distance would be the compression of my skull, BTW),a. What (large!) deceleration would I be experiencing (in m/s2)?b. Over what time interval would that deceleration take place?

- Sasha stands on the ground and tosses a baseball perfectly vertically up to her friend Helge, who catches it by reaching outside the window of his apartment building. She gives the ball an initial speed of vi= 19.7 m/s, and Helge catches it 1.40 s later when it reaches his hands. If Helge were to drop the baseball from rest at this point, what would be its final speed vf when it reaches Sasha’s hands down below? (She catches the ball at the same height from which she tossed it.)For your limit check, investigate what happens to vf as Sasha’s launch speed gets very large (i.e., as vi→∞). This is my question. I am also trying to figure out what formulas I would use to solve it.arrow_forwardA brave cliff diver jumps off the cliff of Tropea, Calabria (Italy), from a height if 16.35 m, from rest.
