Method 1
Hawkeye’s bow is the Hoyt Gamemaster II, which has a draw weight of 35-65 lbs. An arrow weighs around 0.0227 kg. The distance Hawkeye pulled the bowstring was 2 feet.

Low end
35*2 = 70 foot-pounds or 95 joules

sqrt(95*2/0.0227) = 92 m/s

High end
65*2 = 130 foot-pounds or 176 joules

sqrt(176*2/0.0227) = 125 m/s

Average
(92+125)/2 = 109 m/s (whole number)

Method 2
Hawkeye is Street Level physically. That's 200-5000 joules.

Low end
sqrt(200*2/0.0227) = 133 m/s

High end
sqrt (500*2/0.0227) = 664 m/s

Average
(133+664)/2 = 399 m/s (whole number)

Average
(109+399)/2 = 254 m/s
