The velocity just before an object (falling freely under gravity) reaches the ground is equal to the final velocity of the object. The final velocity can be calculated using the equation:
v = u + gt
where:
v = final velocity (in m/s)
u = initial velocity (in m/s) - which is typically taken as 0 for objects dropped from rest
g = acceleration due to gravity (approximately 9.8 m/s^2)
t = time taken to reach the ground
Assuming the object is dropped from rest, the initial velocity u is 0. The time taken to reach the ground can be determined using the equation:
t = sqrt(2h/g)
where:
h = height or distance traveled (in meters)
If you provide the height or distance traveled, we can calculate the velocity just before it reaches the ground.
