Question

answer 5 one please I really need​

Answer 1

1-In the region OA-The volecity increases uniformly with time, thus it represents uniform acceleration.

2-In the region AB-the body moves with a constant speed and hence moving with zero acceleration.

3-In the region BC-the velocity decreases uniformly with time and represent a uniform retardation.

4-Acceleration of the body

$OA = \frac{6 - 0}{4 - 0} = \frac{6}{4} = 1.5m/ {s}^{2}$

5-Retardation in the body

$= \frac{6 - 0}{16 - 0} = \frac{6}{16} = 1m/ {s}^{2}$
