H=m(v²-u²)

2gx

This is the formula for finding the height (H) of an object when given the initial velocity (u), final velocity (v), and acceleration due to gravity (g).

To use this formula, square the final and initial velocities separately (v² and u²). Then subtract the initial velocity squared from the final velocity squared (v² - u²).

Multiply this result by the mass of the object (m).

Finally, divide the entire numerator by 2 times the acceleration due to gravity (2g).

This will give you the height (H) of the object.
