Question

7. Object AB has a momentum of 100 Ns. It then splits into two pieces A and B. Piece A has a momentum of 60 Ns. What is the momentum of object B?

Answer 1

Given the object, AB has a momentum of 100 Ns.

Piece A has a momentum of 60 Ns.

The momentum of object AB is the sum of the momentum of object A with the momentum of object B.

Calculate the momentum of object B.

`\begin{gathered} \text{Momentum AB }=\text{ Momentum A + Momentum B} \\ 100\text{ Ns = 60 Ns + Momentum B} \\ \text{Momentum B = 100 Ns - 60 Ns} \\ \text{Momentum B = 40 Ns} \end{gathered}`

Thus, the momentum of object B is 40 Ns.
