determine the change in momentum of a 200,000 kg Boeing 777 whose speed changes from 450 mph to 80 mph
Solution
Momentum = Speed * Mass
Intial Momentum = 200,000 * 450
Final Momentum = 200,000 * 80
Change = Final - Initial
= 200,000 * 80 - 200,000 * 450
= 200,000 (80-450)
= 200,000 * -370
= -74000000 kg mph
