Ответ:
Momentum = (mass) x (velocity)
On the way to the plate, the momentum of the ball was
(0.15 kg) x (40 m/s this way <==) = 6 kg-m/s this way <==
After the hit, the momentum of the ball was
(0.15 kg) x (45 m/s that way ==>) = 6.75 kg-m/s that way ==>
The CHANGE in momentum was 12.75 kg-m/s that way ==>
That's the momentum that the bat gave it.
Change in momentum = Impulse
Impulse = (force) x (length of time the force lasts)
12.75 kg-m/s = (force) x (0.002 second)
Force = (12.75 kg-m/s) / (0.002 second)
Force = 6,375 Newtons, that way ==>
