What is its velocity just before it reaches the ground
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.
To determine the velocity just before an object reaches the ground, we can use the equation for free-fall motion. Assuming no air resistance, the final velocity (v) can be calculated using the following equation:
v = sqrt(2gh)
Where:
- v is the velocity just before reaching the ground,
- g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth),
- h is the height from which the object is dropped.
Please provide the height from which the object is dropped, and I will be able to calculate the velocity just before it reaches the ground.
