Re: Re: Re: F=MA by Steve
OK, I've convinced myself that force plays an insignificant role at impact. The only way Force (accelertion) can play a role in velocity is when it is multiplied by time
V = Vo + A * t
( A * t being the integral of A over during the time of contact),
t is probably about .001 second. Force plays a role in the velocity of throwing a ball or slinging a ball with a lacrosse stick because of the length of time of force application.
Question: Where did you come up with coefficieant of restitution of 0.55? Is that just because of the composition of the ball? Another question: whould the coefficient of restitution be lower if the bat were made of foam (i.e. it gave a little at contact)?
