Understanding Momentum

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

* Momentum (p) = Mass (m) x Velocity (v)

Calculations

* Mass (m): 250 g = 0.25 kg (convert grams to kilograms)

* Velocity (v): 40 m/s

* Momentum (p) = 0.25 kg x 40 m/s = 10 kg m/s

Answer: The momentum of the ball is 10 kg m/s.
