Question

For the velocity-time graph as shown in figure
incorrect statement is

(1) The average velocity for the entire journey is
2.5 m/s
(2) The average acceleration from 0 s to 4 s is
5 m/s2
(3) The average velocity for the first 4 s is zero
(4) The acceleration at t = 2 s is zero
​

Answer 1

Answer:

The 4th statement is incorrect because at 2secs the slope of v-t graph is not flat and it is inclining with some angle and we know that the slope of v-t graph is acceleration.

Hope it helps you
