Question

A marble is rolling at a velocity 100cm/sec with a momentum of 10,000 g-cm/sec. What is it’s mass?

Answer 1

100g

Step-by-step explanation:

Use the formula,

momentum = mass* velocity

Now substitute the respective values,

10,000g - cm/s = m * 100 cm/s

m = 10⁴ g-cm/s / 100 cm/s

m = 100g

And we are done!
