IF a man jumps off a building that is 90 m high, and gravity is 9.8 m/s, and he weighs 80 kg, then what will his velocity be just as he hits the ground?

SUMMARY
The velocity of a man jumping from a height of 90 meters, under the influence of gravity at 9.8 m/s², can be calculated using the kinematic equation vf² = vi² + 2ax. By substituting the initial velocity (vi) as 0, acceleration (a) as 9.8 m/s², and distance (x) as 90 m, the final velocity (vf) is determined to be 42 m/s upon impact with the ground. The weight of the individual does not affect the calculation of velocity in free fall.
