(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?
(a) Conclusion about acceleration:
The acceleration is increasing.
(Note: The distance varies as the cube of time, i.e., s \propto t^3, which indicates that acceleration is not constant but increasing).
(b) Inference about forces:
The unbalanced force acting on the object is increasing with time.
(Note: Since Force is directly proportional to acceleration (F = ma), and acceleration is increasing, the force is also increasing).
