Answer 1

Answer:

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

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!
