Hello. Will I do?

The gravitational acceleration which glues us to the Earth has
a value of 10^3 cm/sec^2. A decelertion of a=10^-2g =10
cm/sec^2 is nearly unnoticeable. How much time, , would the
Earth take to stop its rotation if the resulting deceleration
were unnoticeable? Earth's equatorial angular velocity is
=2/P=7.3x10^-5 radians/sec; the equatorial linear velocity
is R=0.46km/sec. Thus, =R/a=4600 seconds or slightly over
an hour. But...

The specific energy of the earth's rotation is
E=1/2I/M~=+1/5(r)^2~=4X10^8 ERG/gm.

Where I= the Earth's principal moment of inertia. With a
typical specific heat capacity of Csubp~=8x10^6 ERG/gm/deg.,
the stopping and restarting of the Earth in one day would have
imparted and average temperature increment of delT=2E/Csubp =
117 Kelvins; enough to raise the Earth's ambient temperature
above the normal boiling point of water. It would have been
worse near the surface and at low latitudes; with v=R,
delT=v^2/Csubp = 240 Kelvins. It would be doubtful that the
local populace would have not taken notice of the oceans
boiling away into space.
So there.
