Calculator Travel Time with Acceleration, Constant Speed and Deceleration

Calculating the time required to travel a distance when accelerating from zero to a certain speed, maintaining that speed, and then decelerating to zero. This is a simplified calculation for an idealized travel velocity. When traveling by private or public transport, this scenario will not occur, as the speed changes frequently. This is different, for example, in physical or technical experiments, where the conditions are controlled so that constant acceleration can actually be achieved, the speed can be maintained for a while, and then constant deceleration can be achieved. Simplified models of space travel also follow roughly this pattern. Although the acceleration is not constant here, it can be calculated with an average value.
Please enter the four values ​​and select the appropriate units. When decelerating, a negative acceleration is assumed, so there is no need to enter a negative value. It has to be taken care to ensure that the distance is sufficient to reach the speed.

An example with very simplified values: a moon rocket accelerates at an average force of 0.3 g to a speed of 2 kilometers per second, or 2000 m/s. Let's assume that it decelerates just as much as it accelerates, so the value here is -0.3 g. The distance to be covered is 386000 kilometers. The rocket then needs a total of 2 days, 5 hours, and 47 minutes for the flight. Acceleration and deceleration each occur at a speed of 680 kilometers.
