h = v 0 y 2 2 g . h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.

Height of Rectangular Objects Divide the volume by the product of the length and width to calculate the height of a rectangular object. For this example, the rectangular object has a length of 20, a width of 10 and a volume of 6,000.

So, “H/S = h/s.” For example, if s=1 meter, h=0.5 meter and S=20 meters, then H=10 meters, the height of the object.

A reproduction of Wilhelm Schickard’s Calculating Clock. The device could add and subtract six-digit numbers (with a bell for seven-digit overflows) through six interlocking gears, each of which turned one-tenth of a rotation for each full rotation of the gear to its right.

Another simple technique to calculate the duration between two times in Excel is using the TEXT function:

1. Calculate hours between two times: =TEXT(B2-A2, “h”)
2. Return hours and minutes between 2 times: =TEXT(B2-A2, “h:mm”)
3. Return hours, minutes and seconds between 2 times: =TEXT(B2-A2, “h:mm:ss”)

To calculate elapsed time:

1. Count on in minutes from the earlier time to the nearest hour.
2. Count on in hours to the hour nearest to the later time.
3. Count in minutes to reach the later time.

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

DATEDIF is not a standard function and hence not part of functions library and so no documentation. Microsoft doesn’t promote to use this function as it gives incorrect results in few circumstances. But if you know the arguments, you may use it and it will work and in most of the cases will give correct results.

Here are a few Excel DATE formula examples: =DATE(2015, 5, 20) – returns a serial number corresponding to 20-May-2015. =DATE(YEAR(TODAY()), MONTH(TODAY()), 1) – returns the first day of the current year and month. =DATE(2015, 5, 20)-5 – subtracts 5 days from May 20, 2015.

Add or subtract days from a date

1. Enter your due dates in column A.
2. Enter the number of days to add or subtract in column B. You can enter a negative number to subtract days from your start date, and a positive number to add to your date.
3. In cell C2, enter =A2+B2, and copy down as needed.

The TODAY function takes no arguments. The TODAY function takes no arguments, and returns the current date, updated whenever a worksheet is changed or opened. You can also use F9 to force the worksheet to recalculate and update the value.

Except the above formula, you can also apply this formula: =TEXT(A2, “mmm”) & “-” & TEXT(A2, “yyyy”). 2. In above formulas, A2 indicates the date cell that you want to use, and the separator “-” is used to separate the month and year, you can change it to any other delimiters you need.
