The displacement of a body is proportional to the cube of the time lapsed. The magnitude of the acceleration is:
A. increasing with time
B. decreasing with time
We know that,
Now, Velocity = …….2
From equations 1 and 2, we get,
Now, we also know that,
Acceleration = …….4
From equations 3 and 4, we get,
Since, acceleration is directly proportional with time, so it increases with time.
Hence option A is correct.

An object is dropped from rest at a height of 150 m and simultaneously another object is dropped from rest at a height 100 m. What is the difference in their heights after 2 s if both the objects drop with same accelerations? How does the difference in heights vary with time?NCERT Science - Exemplar
