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 or zero ?
(b) What do you infer about the forces acting on the object ?

Explanation

There is an uneequal change of distance in an equal interval of time. Thus, the given object .
is having a non uniform motion since the velocity of the object increasing with time , the acceleration is increasing.
The object is in accelerated condition. According to Newton.s second law of motion, the force acting on an object is directly proportional to the acceleration produced in the object is directly proportional to the acceleration produced in the object , so we can say unbalanced force is acting on the object.
