Given that the acceleration of the object is

The final velocity is

The initial velocity is

We have to find displacement and distance.
Let the displacement be denoted by S and the distance by d.
First, we need to calculate time in order to find distance and displacement.
The time taken will be

(a) The displacement will be

(b) The initial speed will be equal to the initial velocity.
Thus, the distance will be 16.469 m.
(c) The initial velocity of the second object is

The final velocity of the second object is

The acceleration of the second object is

The time taken will be

We have to find the displacement of the second object.
Let the displacement of the second object be denoted by S'.
The displacement of the second object will be

(d) The initial speed of the object will be

We have to find the distance.
Let the distance be denoted by d'.
The distance of the second object will be
