Whats the terminal velocity of a pineapple?

I dont really know how to calculate drag :/
Im handicapped, remember

Its for a book, and the book is for a project for school
They picked a random subject and the subject was a killing someone with a pineapple or something

simple google search
that's for terminal velocity, it's derived from the force and drag equation, look at the drag equation as well

Not sure. I'll contact some of my AE friends and ask them. My hunch is that a pineapple would not reach 104.11 m/s. My reasoning is that, all things equal, terminal velocity tends to increase when you have an object with a higher mass which is closer in shape to a sphere. Google tells me that a bowling ball has a terminal velocity of around 74 m/s. A bowling ball is both heavier and more spherical than a pineapple, meaning you would expect a pineapple to fall at less than 74 m/s.
There is another flaw with the question you're asking here though:

I'm not sure how you actually went from pineapple speed to impulse force. Remember that impulse is F_avg * change in time. How did you determine how long a pineapple takes to impart its momentum into a human skull?

I don't think it is really. All the pines face outwards and increase drag, like little parachutes.
The leaves on top do the same if dropped upside down.
Maybe it's better if you chop the pineapple into cubes and drop it, like a pineapple shotgun.

we should outlaw pineapples
