To calculate height in a free fall problem, it's essential to first define the parameters of the situation, such as initial velocity and time of fall. The commonly used formula for height is h = 0.5 * g * t², where g represents the acceleration due to gravity. Providing specific details about the problem, such as the object's starting height or any initial velocity, is crucial for deriving the correct formula. Without this information, it's challenging to offer a precise solution. Clear problem statements lead to more accurate calculations in free fall scenarios.
