Hey here r the answers....

1. acceleration is the rate of the measure of the change in the velocity of the moving object per unit time. Si unit is ms^ -2 = m /s^2

(i ) if the object moving along the line is positive.same direction.

(ii) if the object is moving in the opposite way it is negative.opposite direction.

2 . the motion of a freely moving body is the example of uniform acceleration.
