Question #53169

Answer 1

60.72 joules

Explanation:

Kinetic energy of the goose is given by the relation `1/2mv^2` joules.

WHERE
m is the mass of the goose in kilograms and v is the velocity of the goose in meter/second .

GIVEN:
m=18.9 lb.
1 pound=0.45 kilograms
18.9 lbs = 18.9 x 0.45 kilograms `=>`8.5 kg

v =8.4 miles/ hr
1 mile/hour=0.45 m/s
8.4 miles/hr=8.4 x 0.45 m/s `=>`3.78 m/s

KINETIC ENERGY :

K.E= `1/2xx8.5 xx3.78^2=>60.72 J`
