Be interesting to see the bow that could handle those arrows!
According to you the KE would increase using the same bow
Dan
Yes, if you could build a bow that could shoot both a 2# and a 20# arrow, the 20# arrow would have more ke than the 2#. Of course the 20 pounder would be flying much slower but it would carry more ke.
A train moving at1 mile per hour has far more ke than than 600 grain arrow flying 400 ft/sec.
KE goes up with the square of velocity. The 20# arrow, the velocity would go down compared to the 2# arrow. Velocity is the significant factor in KE, where momentum, it does not go up by the square of velocity, and mass is the significant figure. This is statics and dynamics 101 sylvan. Fairly simple stuff. Surprised your having such a hard time getting a handle on it.
