Answer:
, assuming that the object was initially not moving.
Step-by-step explanation:
Under the assumptions, the acceleration
of this object will be constant:
.
The initial velocity
of this object will be
since this object was initially not moving:
.
Let
denote the displacement of this object. This object has been accelerating for
. Apply the SUVAT equation
to find the displacement of this object in that much time:
.
In other words, the displacement of this object would be
(displacement is negative since this object is now below where it initially was.)
