Easy Kinetic Energy question

[From: ] [author: ] [Date: 11-07-07] [Hit: ]
8 lb x 1kg/ 2.21 lb = 9.V = 9.50 mi/h x 1h/3600s x 1609.3 meters/mi = 4.KE = 1/2 x 9.......
The goose has a mass of 21.8 lb (pounds) and is flying at 9.50 miles/h (miles per hour). What is the kinetic energy of the goose in joules?

-
KE = 1/2MV^2

M= 21.8 lb x 1kg/ 2.21 lb = 9.86 kg

V = 9.50 mi/h x 1h/3600s x 1609.3 meters/mi = 4.25 m/s

KE = 1/2 x 9.86 Kg x (4.25 m/s)^2 = 89.0 J
