The mass of this bag of cement in S.I. units (kg) is equal to 0.062 kilograms.
<u>Given the following data:</u>
To calculate the mass of this bag of cement in S.I. units (kg):
<h3>How to convert to S.I. units.</h3>In Science, kilograms (kg) is the standard unit of measurement or S.I. units of the mass of a physical object. Thus, we would convert the value of the mass of this bag of cement in grams to kilograms (kg) as follows:
<u>Conversion:</u>
1000 grams = 1 kilograms.
62 grams = X kilograms.
Cross-multiplying, we have:
X =
X = 0.062 kilograms.

Answer:
Explanation:
Given
Initial velocity of first billiard ball
Initial velocity of second billiard ball
After collision first ball comes to rest
suppose m is the mass of both the balls
Conserving momentum to get the speed of second ball after collision
Initial momentum
Final momentum
where and
are the speed of first and second ball respectively
thus speed of second ball after collision is equal to speed of first ball before collision
