Answer:
The velocity of the weight just before it hits the floor is 43.904 m/s
Explanation:
Free Fall of Objects
If an object is dropped from rest in free air, it falls with a constant acceleration called the acceleration of gravity, which value is g = 9.8 m/s^2
The final velocity of a free-falling object after a time t is given by:
[tex]v_f=g.t[/tex]
Note this equation does not depend on the weight of the object. We know the weight falls by t=4.48 seconds, thus:
[tex]v_f=9.8\ m/s^2\cdot 4.48\ s[/tex]
[tex]v_f=43.904\ m/s[/tex]
The velocity of the weight just before it hits the floor is 43.904 m/s
