Question

A bird sitting on a hinged perch takes off from the perch, pushing the perch

in the opposite direction. The momentum of the perch

Answer 1

The momentum of the perch is equal to it's own momentum gather to take off

Step-by-step explanation:

According to the Newton third law of motion which state that: in every action, there will be an equal and opposite reaction.

This is the law that helps us to walk, paddle boats e.t.c.

And momentum is always conserved. Therefore, the momentum of the perch is equal to it's own momentum gather to take off
