A moving body is covering a distance directly proportional to the square of time. The acceleration of the body is:
We know that, Distance …..1
Now, Velocity = …..2
From equations 1 and 2, we get,
Velocity Time …..3
Now, we also know that, Acceleration = …..4
So, from equations 3 and 4, we get,
Acceleration
Acceleration = Constant
Hence, option D is correct
