Thanks to the calculator, we can calculate:
NPV (Net Present Value) - sum of discounted net cash flows
PI (Profitability Index) - investment profitability

With this calculator, you can calculate the velocity of a body thrown vertically after a specified time and the initial velocity given to the body. You will also calculate the time elapsed from the moment of the throw to reach a certain speed, the time the body flies to the return to the place of the throw and the time after which the body reaches its maximum height. The calculator will also help you calculate the height at which the body is located after a certain time and will calculate the maximum height that the body will reach. The calculator also allows you to estimate the gravitational acceleration which can be useful in determining where the body was thrown.

With the percentile calculator you will calculate the percentile position and find the value. Percentile or centile is a measure in statistics that indicates a value for which P Percentage of the Population is equal to or less than that value and 100-P is greater.
