Question

The velocity time graph shown below represents motion of body
a:calculate average acceleration of entire journey

Answer 1

pls mark as brainliest if this has helped u

Answer 2

Answer:

Explanation: Average acceleration (a) = (v - u) /t

Here v = 7 m/s , u = 0 and t = 30 sec.

a = (7 - 0)/30 = 7/30 = 0.23 m/s^2
