<h2>Answer:</h2>
He saves 13.2 minutes
<h2>Explanation:</h2>Hey! The question is incomplete, but it can be found on the internet. The question is:
How many minutes did he save?
Let's call:
We know that the 135 miles are on the interstate highway where the speed limit is 65 mph. From this, we can calculate the time it takes to drive on this highway. Assuming Richard maintains constant the speed:
Today he is running late and decides to take his chances by driving at 73 mph, so the new time it takes to take the trip is:
So he saves the time :
In minutes:

See answer below
Explanation:
Hi there,
To get started, recall the Center of Mass formula for two masses:
where m is mass and x is displacement <em>from the center of the shape.</em>
Since masses at the center of a geometric shape have a displacement (x) value of 0, as the mass is already of the center, and does not affect Xcm. So, we can disregard the central mass, hence we use the above formula for two masses.
We can arbitrarily define left to be a negative (-) displacement, and vice versa for right direction. We proceed with the formula:
Since we defined left (-) and right (+), we notice the center of mass is (+) value. This makes sense, as there is slightly more mass on the right side. Hence, you should place a support 1/6 of the rod's length away from the rod's center.
Study well and persevere.
thanks,
