Question

A ball moving at a velocity of 10 meters/second has a momentum of 8.0 kilogram meters/second. What is its mass?
A. 8.0 × 10^-2 kilograms
B. 0.8 kilograms
C. 8.0 kilograms
D. 80 kilograms

Answer 1

momentum=mass*velocity

Answer 2

Well momentum is found my multiplying Mass and Velocity...so

\[P = MV\]

You have P *momentum* andV *velocity so we have

\[M = \frac{ P }{ V }\]

when putting in your numbers you have...

\[M = \frac{ 8 }{ 10 }\]

So what is your mass?

Answer 3

0.8 so its b

Answer 4

yes

Answer 5

thank you

Answer 6

Good job!
