Understood...
Agreed ... there is no way to measure/calculate for Fground or Δt. Sure would have been interesting activity if we could.
Thanks for helping me work through it. If okay will print this page for my students. With your help it has been instructive. Don't mind showing my...
Yes Kuruman that is what I was shooting for... I total missed mark on my second formula. The net force equation was my problem. Blew that one.. amateur hour. :redface:
Given this correction FNet would equal 0; hence,
Fground on ball = FGravity = mg so...
mgΔt = mv
mgΔt = m (0 - (2gh)1/2)...
Thanks kuruman for you replay ... this helps me flush this out in my mind and try to salvage this.
1) Concerning "F" in impulse equation, am I way off at proposing that the equation 2 in original post address this unknown. Would "F" = mg + ma (mg is force applied by ground to bowling ball...

This http://www.alcaweb.org/cgi-bin/WebObjects/ALCA.woa/wa/resource?id=jQ3f23g01p" takes one to the assignment. Students had to determine specific equations based on list and in turn derive a working equation to calculate the total time it took for a bowling ball to come...
