Question

the velocity-time graph of an object is shown in the figure (a) state the kind of motion that object has from AtoB and from B to C. (b) identify the part of graph where the object has zero acceleration. Give reason for your answer. (c) identify the part of garph where the object has negative acceleration. Give reason for your answer​

Answer 1

Answer:

I think u also need to upload the figure along with the textual question, so that we can answer.

Answer 2

Answer:

(a) Region AB of graph shows uniform motion but the region BC shows non-uniform motion.

(b) In region AB of the graph the object has zero acceleration because velocity in this

region is constant at 40 m s-1

(c) In region BC the object has negative acceleration because the velocity is falling from 40 m s1

at point B (time = 25 s) to zero at point C (time = 45 s).
