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

0.8 kilogram

Explanation:

Mass: This can be defined as the quantity of matter a body contained. The S.I unit of mass if kg.

From the question,

M = mv................. Equation 1

Where M = momentum, m = mass. V = velocity

make m the subject of the equation

m = M/v.............. Equation 2

Given: M = 8.0 kilogram meters/second, v = 10 meters/second

Substitute these values into equation 2

m = 8.0/10

m = 0.8 kilogram

Answer 2

The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

The solution would be like this for this specific problem:

M=P/V

M=8/10

M=0.8
