please answer this questio

Answer 1

Answer:

OA = uniform acceleration

AB = constant velocity

BC= uniform de acceleration

Explanation:

OA is uniform acceleration because there is constant increase in velocity. Consider a car moving with velocity 10m/s when time was 5s then after 3s

i-e 7s in total ,velocity of car becomes 12m/s after another 3s ,velocity becomes 14m/s and so on .So the velocity is increasing with uniform rate with respect to time .This shows uniform acceleration .

AB represents constant velocity because car is moving with constant velocity .E.g Car is moving with velocity 40m/s when time= 3s when t= 6s velocity is still 40m/s .When time becomes 8s velocity is still 40m/s .That is velocity doesn't change with time .

BC represent uniform de acceleration because velocity decreases with constant rate .
