An arrow, starting from rest, leaves the bow with a speed of 25.0 m/s. If the average force exreted on the arrow by the bow were doubled, all else remaining the same, with what speed would the arrow leave the bow?
The kinetic energy of the arrow,
K = mv^2/2
(where "v^2" reads "v squared"), is equal to the work done on it by the string of the ...
