Aball 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

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

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

do you have a formula possibly
