Understanding Momentum

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

* Momentum (p) = mass (m) × velocity (v)

Calculation

* Mass (m) = 2.4 kg

* Velocity (v) = 3.0 m/s

* Momentum (p) = 2.4 kg × 3.0 m/s = 7.2 kg·m/s

Answer: The starting momentum of Glider 1 is 7.2 kg·m/s.
