The displacement of a body is proportional to the cube of the time lapsed. The magnitude of the acceleration is:

Question

Philoid · Accepted Answer

We know that,

Displacement …….1

Now, Velocity = …….2

From equations 1 and 2, we get,

Velocity …….3

Now, we also know that,

Acceleration = …….4

From equations 3 and 4, we get,

Acceleration time

Since, acceleration is directly proportional with time, so it increases with time.

Hence option A is correct.
