Understanding Momentum

Momentum (p) is a measure of an object's mass in motion. It's calculated by:

* p = m * v

Where:

* p = momentum (kg*m/s)

* m = mass (kg)

* v = velocity (m/s)

Solving for Velocity

1. Rearrange the formula: We need to solve for velocity (v), so rearrange the equation:

* v = p / m

2. Plug in the values:

* v = 17.5 kg*m/s / 2.5 kg

3. Calculate:

* v = 7 m/s

Answer: The bird is flying at a velocity of 7 m/s north.
