Question

(1) Time interval in which acceleration will
be zero.
(ii) Acceleration at t = 5 s.
(iii) Change in velocity during time interval
t = 4s and t = 8 s.​

Answer 1

Answer:

1) time is 2 to 4.

2) 12.5 m/s².

3) 25 m/s.

Explanation:

3) velocity = area under the acceleration graph.

area = 1/2 b×h

= 1/2 4×12.5

= 25 ans.
