Calculator Acceleration on a Straight Track

Calculation of acceleration when accelerating to a speed in a straight line of a specified length. A deceleration is a negative acceleration, this can also be calculated. Please enter two values to get the third one. In addition, the duration is calculated in seconds.
The formulas are:
acceleration = velocity² / (2*distance)
duration = √ 2*distance / velocity

Example 1: if you accelerate from 0 to 100 km/h over a distance of 100 meters, the acceleration is 0.4 g.

Example 2: if you drive against a wall at 40 km/h and the crumple zone of the car is depressed by 50 centimetres, the braking effect is 12.6 g.
