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. The data clearly shows that the distance covered at any time is the previous time intervals. Therefore, the acceleration of the object is .
b. Here the mass of the object remains , the increasing acceleration implies that the force acting on the object is .
