"Mean" means "average"= (distance covered) divided by (time to cover the distance)= ( 90 / 4.5 ) = 20 feet per second
They are the same .
Divide the distance by the time. In this case, the answer will be in meters/second. If you want to convert that to the more common kilometers per hour, multiply this result by 3.6.

Distance covered in nth second means the distance covered in that particular second . It cannot be more than the distance covered in n seconds which means the distance covered in a total time of n seconds.
None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.None.Speed is the distance covered per unit of time. If no distance is covered then the speed is 0.

Assuming the object is in free fall and neglecting air resistance, the distance an object falls in 2.56 seconds can be calculated using the formula for free fall: d = 0.5 * g * t^2. Given that the acceleration due to gravity is approximately 9.81 m/s^2, the distance fallen can be determined by plugging these values into the formula.
A stone falls freely from rest The total distance covered by it in the last second of its motion equals the distance covered by it in the first three seconds How long does the stone remain in air?
4 Seconds
distance = speed x time so the distance is just the speed of the stone x 8 seconds
128
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.

The velocity of a freely falling object 5 seconds after being dropped is approximately 49 meters per second (m/s) downwards. This is the velocity an object reaches due to the acceleration of gravity (9.8 m/s^2) acting on it.
The average constant speed of the object between 2 and 5 seconds is the total distance covered divided by the time elapsed. If you have the distance covered during this time interval, divide it by 3 seconds (5s - 2s) to get the average constant speed.
