Question

A marble rolls with a speed of 15 m/s and has a momentum of 0.15 kg*m/s. What is its mass?​

Answer 1

Answer:

m = 0.01 kg

Explanation:

Given that,

Momentum of the marble, p = 0.15 kg-m/s

Speed of the marble, v = 15 m/s

We need to find its mass. We know that,

Momentum, p = mv

Where

m is the mass

$m=\dfrac{p}{v}\\\\m=\dfrac{0.15}{15}\\\\m=0.01\ kg$

So, the mass of the marble is equal to 0.01 kg.
