A moving body is covering a distance directly proportional to the square of time. The acceleration of the body is:
A. increasing

B. decreasing

C. zero

D. constant

Answer :

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
