QUESTION:
An object starts from rest and falls under the influence of gravity. Draw graphs of (a) its speed and (b) the distance it has fallen, as a function of time from t = 0 to t = 5.00 s. Ignore air resistance.
ANSWER:Step 1 of 2
Part a
We are required to draw the speed and time graph of the falling object.
The object falls from rest, so the initial speed is
Let the final speed be .
It falls under the gravity influence, so the equation of motion is,
( since
)
Find v values from to
s.
The speed and time plot is shown below. The plot is done using OriginPro.
The plot is a straight line, since is a straight line equation.
