Question

What is the mass of a ball rolling at 4.5m/s if it's momentum is 3.5 kg•m/s?​

Answer 1

The ball has a mass of 7/9 kg

Step-by-step explanation:

Momentum is just mass times velocity, so to find its mass, we can simply divide the given momentum by the given velocity.

`3.5 kg(m)/(s) / 4.5(m)/(s) = (7)/(9)kg`
