What type of acceleration does a trapezium on a velocity time graph represents?

Why zero in front of decimal?
While writing the point (period symbol) may not be legible and so zero is added. It is still possible to have an illegible point (period sign). Just another safety mechanism. Also used to line up digits during mathematical operations.
When was the number zero first used?
The first traces evidence that has been noted on the zero was found in the 3rd century B.C.E. 5,000 years ago. The first recorded zero is attributed to the Babylonians. They wrote in cuneiform and their zero was represented by a slanted double wedge that was inserted between cuneiform symbols for numbers. Then after a long period where nobody else used zero the Mayans independently invented zero in the 4th century CE. Their zero was represented by a black football shaped figure that looks like it has a white smiley in the center. The final independent discovery of the zero was in India in the middle of the 5thcentury. Their zero was represented by a dot. It later spread to China,Arabia, and Europe in which it became the zero we know now as an open circle.
