if baseball is hit in the same spot with the same bat in the sweet spot and same swing speed i have to think the faster the pitch the further it will go

Vexit = q x Vpitch +(1 +q) x Vbat
q: Speed of the ball leaving the bat.
Vbat: Speed of the bat at the point of impact.
Vpitch: Speed of the pitched ball.
q (Collision Efficiency): This coefficient depends on the "liveliness" of the bat (COR - Coefficient of Restitution).
For wood bats,
is generally 0.1 to 0.2 (0.2 is a perfect collision).
For non-wood bats,
can be higher due to the "trampoline effect".

yep. essentially bat speed is 6 times more important than pitch speed when talking exit velo
for exit velo
every 1 mph of bat speed gets you roughly 20% more exit velo.
that is where the 1.2 x bat speed comes from
then you can divide pitch speed by 4 and add it to get roughly the exit velo
so say you have a HS kid that has 65mph bat speed and is facing a pitcher throwing 80 and he hits it perfect perfect
(65 * 1.2) + (80/5)=
78 + 16= 94
this equation holds true for wood and bbcor. Difference is the much larger sweet spot on bbcor so much more forgiving.
for USSSA bats
they allow 15% more rebound effect...hence the 1.15 rating. BBCOR is 0.5 rebound effect, which is roughly the same as wood
for USSSA composite bats its 8-10mph more in the drop 5 vs bbcor in terms of exit velo
remember every mph of exit velo adds 4-6 feet of distance at 28* launch angle. optimal is ~30-35 for max distance. 10-25* provides the best opportunity for a base hit.
