A goose is flying south for the winter at a constant speed. Keep in mind that one mile is 1.61 km, and one pound is 454 g.The goose has a mass of 20.1 lb and is flying at 9.60 miles/h. What is the kinetic energy of the goose in joules?

Respuesta :

Answer:

kinetic energy =  84.0260 joules

Explanation:

given data

one mile = 1.61 km

one pound = 454 g

mass = 20.1 lb = 9.1172 kg

flying velocity = 9.60 miles/h = 9.60 × 1.61 × [tex]\frac{5}{18}[/tex] = 4.2933 m/s  

solution

we get here kinetic energy that is express as

kinetic energy = 0.5 × m × v²   .........................1

put here value and we get

kinetic energy = 0.5 × 9.1172 × 4.2933²

kinetic energy =  84.0260 joules
