Find the total momentum of the following system contains a
duck and three baby ducks moving to the right
If the mass of the duck is 0.5 kg moving with 2m/s and each of
the three ducks has a velocity of 1.5 m/s and a mass of 0.1 kg.

Answer 1

The total momentum of the system is 1.45 kg*m/s.

Step-by-step explanation:

The total momentum of the system is given by:

`p_(T) = p_(d) + p_{b_(1)} + p_{b_(2)} + p_{b_(3)}`

`p_(T) = m_(d)v_(d) + m_{b_(1)}v_{b_(1)} + m_{b_(2)}v_{b_(2)} + m_{b_(3)}v_{b_(3)}`

Where:

m: is the mass

v: is the velocity

d: is for duck

b₁: is for baby duck one

b₂: is for baby duck two

b₃: is for baby duck three

`p_(T) = 0.5 kg*2 m/s + 0.1 kg*1.5 m/s +0.1 kg*1.5 m/s + 0.1 kg*1.5 m/s = 1.45 kg*m/s`

Therefore, the total momentum of the system is 1.45 kg*m/s.

I hope it helps you!
