Absolutely, as anomilies can show inconsistencies with data and hypothesis they may have and may actually assist in refining the accuracyof their ideas by not only encompassing the most commonly-occuring phenomena, but also the more seldom occuring scenarios as well.
Answer:
speed of the arrow as it leaves is 41.05 m/sec
Explanation:
We have given mass m = 0.285 kg
Average force F = 182 N
Distance traveled d = 1.32 m
We know that work done = force
distance
Sp work done = 
Now according to work energy theorem work done will be equal to kinetic energy
So 


v = 41.05 m/sec
So speed of the arrow as it leaves is 41.05 m/sec
