Question

the following is the distance-time table of an object in motion.​

Answer 1

Hello!

__________

Here is your answer

____________________

a) The graph represents a curve, thus the object has non uniform motion. The velocity of the object increases with time, so acceleration is increasing.

b) Newton's second law of motion:

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

Thus, the force acting on the object also increases.
