Question

a space shuttle weighting 15000kg and moving with a velocity of 144 m/s drops off its two rockets each weight is 2000kg if the velocity increase to 180m/sec as a consequence calculate the change in momentum ​

Answer 1

Answer:

Explanation:

Mass of shuttle=15000 kg=M1

Mass of rockets=2000*2 kg=4000 kg

Velocity of the shuttle=144 m/s=V1

Velocity of shuttle after detaching the rockets=180 m/s=V2

Mass of shuttle without the rockets=15000-4000=9000 m/s=M2

Initial Momentum=M1*V1

=15000*144=2160000

final Momentum=M2*V2

=9000*180=162000

Change in Momentum= M1*V1-M2*V2

=2160000-162000

=2098000 kg m/s
