Question

velocity (ms)
05. The velocity time graph of an object is as
shown below
(i) Identify the kind of motion of an object
between time 0-2.5 sec, and 7.5-10 sec.
(ii) With what velocity the object is moving at
1=6 sec?
(iii) Calculate the acceleration of the object in
the following cases
(a) Between the 4th and 7th second
(b) During 7.5th to 10th second​

Answer 1

Answer:

I) 0-2.5 sec uniform acceleration and 7.5-10 sec uniform deceleration

ii) at 6secs it's velocity is 1m/s

iii) a) 4th to 7th the acceleration is 0

b) 7.5th to 10th the acceleration is (-0.4)
