Question

How to find net displacement and the total distance covered
​

Answer 1

Explanation:

To solve, you need two separate definite integrals: From the starting point (t = 1) to zero (t = 2), From the zero (t = 2) to the ending point (t = 3).

Answer 2

Explanation:

The two quantities are equal when the motion occurs without any change in direction. In that case, the individual displacements point in the same direction, so the magnitude of the net displacement is equal to the sum of the magnitudes of the individual displacements (the total distance).
