The goose has a mass of 22.1 lb (pounds) and is flying at 8.30 miles/h (miles per hour). what is the kinetic energy of the goose in joules?

M = 22.1 lbm, the mass

v = 8.3 mi/h, the speed

Note that

1 mi/h = (5280 ft/mi) * (1/3600 h/s) = 1.4667 ft/s

Therefore

v = 8.3*1.4667 = 12.1736 ft/s

By definition, the KE (kinetic energy) is

KE = (1/2) * m*v²

= 0.5 * (22.1 lbm) * (12.1736 ft/s) ²

= 1637.57 lb-ft

Because 1 lb-ft = 1.35582 J, the KE is

KE = 1637.57*1.35582 = 2220.3 J

Answer: 2220.3 J
