The following is the distance-time table of an object in motion:

(a)What conclusion can you draw about the acceleration ?Is it constant. Increasing decreasing ir zero? (b)What do you infer about the force acting on the object?

Explanation

From the given table,initial speed to the object is zero.
`s=ut+(1)/(2)at^(2)`
Here,u=0
`therefore s=(1)/(2)a^(2)`
`therefore a=(2s)/(t^(2))`

(a)From 3rd column of the above table it is clear that the acceleration is increasing uniformly with time.
(b)Force is directly proportional to the acceleration (2nd law of motion)
`therefore force acting on the object are increasing uniformly with time.
