Question

19. The following is the velocity line graph (fig. 1.38 ) for a moving body Find :​

Answer 1

Answer:

please mark me as brainlyest

Explanation:

BC represent uniform velocity because the velocity remains same during B to C point. From graph, we see that the velocity of the body at point C=40km/h

(ii) Acceleration between A and B=  slope of line AB as it is the rate of change of velocity

=(3−0)h(40−20)km/h=6.66km/h2

(iii) BC represent uniform velocity, so acceleration acting on the body between B and C is zero.
