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?
0.7848 meter
490 meters
A freely falling object will fall approximately 122.5 meters in 5 seconds assuming no air resistance. This value can be calculated using the formula d = 0.5 * g * t^2, where d is the distance fallen, g is acceleration due to gravity (approximately 9.81 m/s^2), and t is the time in seconds.
The ratio of distances traveled by a body in free fall starting from rest in the first and third seconds is 1:9. This is because the body's distance traveled in each second increases in proportion to the square of the time elapsed.
Assuming the object is falling under gravity, it will fall approximately 78.4 meters in 4 seconds. This is based on the formula: distance = 0.5 x acceleration due to gravity x time squared.

A freely falling Ball has the acceleration of 9.8 m/s/s so after 5 seconds its velocity will be: t=5s a=9.8m/s/s v=5s * 9.8m/s/s =49 m/s
A joint in which the opposing bony surfaces are covered with a layer of hyaline cartilage or fibrocartilage and in which some degree of free movement is possible.
With the information given, all that can be said is that the distance is greater than the distance the object traveled in the previous second.
that makes the item weightless. it will float freely not gaining or loosing altitude.
The speed of a freely falling object 10 seconds after starting from rest is approximately 98 m/s. This is because in free fall, the acceleration due to gravity is approximately 9.8 m/s^2, so after 10 seconds, the object would have reached a speed of 98 m/s.
