Answer:
vi and vtop = 0
Explanation:
Free fall is a motion of a body in which the only force acting of the body is the Gravitational Force. In this motion body moves with constant acceleration i.e acceleration due to gravity.
When an object is thrown downward from a non zero height say h the motion is referred to as free fall with initial velocity of object beign zero. Hence v=0
In free fall, an object have the slowest speed at the beginning of the motion which is at the top before the object starts to fall. [tex](V_i \ and \ V_{top})[/tex]
During a free fall, the object subjected to only acceleration due to gravity. The velocity of object increases as the object moves downwards and eventually becomes maximum before the object hits the ground.
The final velocity of the object is the greatest while the initial velocity of the object at the top before the free fall is the slowest.
[tex]V_f > V_i \ or\ V_{top}[/tex]
Thus, we can conclude that during a free fall, the velocity of the object increases downwards. The slowest speed can found at the beginning of the motion.
