Answer 1

Answer:

Explanation:

1) non uniform motion

2) AB portion has zero velocity as slope is zero so it is at rest.

3) slope of s-t graph gives velocity

OA ⇒ 30/10 = 3 m/s

AB ⇒ 0 m/s

BC ⇒ 20/10 = 2 m/s

4) CD  has 5 m/s velocity but in opposite direction as slope is negative but it is the maximum velocity even its in opposite direction
