What if earth slowed it's rotation a full day went from 24 hours to 36 hours? Would there be that much of a difference or would the planet die along with all or most of life here?

Suddenly? We'd be screwed. The atmosphere would keep rotating at 24 hours per day, giving us winds ranging up to 500mph. Not that we'll care, because the oceans will be sloshing over land and drowning us. So let's assume it happens slowly or that we just magically change to 36 hours per day and all the excess kinetic energy is spirited away. Now what?
I don't think that 36 hours would be catastrophic. Most plants and animals can deal with changing day night cycles from summer to winter without a huge amount of trouble.
The equatorial oceans would get shallower and the polar oceans would get deeper. My instinct is to say that hurricanes would get less severe, because of the slowed rotation and less water, but it's also possible that the shallower tropical waters would get warmer and that would drive hurricanes to be stronger. Nevertheless, I'm going with an overall weakening of hurricanes.
Currently reading Immanuel Velikovsky's "Worlds in Collision",
which addresses that concept 'earth slowing down'. Succinctly?
The oceans would buckle up like a giant wall of jello miles high and
the continental plates would tear from the mantle like a skin of peach.

The earth's rotation is slowing down and the orbit of the moon is slowly changing due to the energy of the system as seen in the tides etc. However, the rate of change is very slow by our standards. It will be a long time before the rotational period is 36 hours.
Velikovsky's musings are generally rather off the mark.
we'd fall off
duh

No, "our gravity" is a result of mass, not rotation.
Well there is no reason to assume the force that caused the earth equatorial velocity to slow by 300mph would not also apply to the atmosphere, oceans and anything else not nailed to the ground.
If what you say were true every person on earth would be sudden chucked at 300mph towards the east. And presumably dead on impact. No time to worry about tsunamis, earthquakes and hurricane winds.
I would work three 13 hour days, have the rest of the week off.
I would get alot of sleep.
My newborn will be very old when he reaches 50

But the Republicans would still deny it.

Actually, the length of a year has nothing to do with the earth's rotation so your newborn would be 50 (in current years) when he was 50 (in 36 hour rotation years).

Really? Dang, you're smart!

Since an hour is typically defined as 1/24 of a day, then it can never take 36 hours for the Earth to make a full rotation no matter how much it slows down.
I'd still be concerned about the icecaps.
I thought 1 hour was 60 minutes?
I've read the Velikovsky books. My favorite is Oedipus and Akhnaten. They are all pretty hard to find. There's a site that keeps a lot of his stuff alive though.
My geology and astronomy profs read him during the doctoral work. Geology guy seemed to like him and the astronomy guy said he was a complete idiot.
Anyone study Velikovky's research and it's validity?

Its.
Thanks for the contribution.

I'd need a long nap every day.
I'd run a sub 2 marathon.
