What is the time required for an object starting at rest to fall freely 500 meters near earth surface

The time required for this object to fall freely is 10.10 seconds.

Given the following data:

We know that acceleration due to gravity (a) for an object in free fall is equal to 9.8 meter per seconds square.

To find the time required for this object to fall freely, we  would use the second equation of motion.

Mathematically, the second equation of motion is given by the formula;

Where:

Substituting the values into the formula, we have;

Time, t = 10.10 seconds

Therefore, the time required for this object to fall freely is 10.10 seconds.
