A particle moved along the `X-`axis according to the graph shown in Figure. Choose the incorrct options.

A

The particle did not move in straight line from `t=0 s` to `t=5s`.

B

The magnitude of displacement of particle from `t=0s` to `t=5s` is `2 m`.

C

The average speed of particle from `t=0s` to `t=5s` is `0.8 m//s`

D

The speed of particle is zero somewhere between `t=3s` to `t=4s`.

Text Solution

Verified by Experts

The correct Answer is:
A
`(1)` since the particle is moving along `x-`axis it is straight line.
`(2)` `s=x_(f)-x_(i)=2-0=2m`
`(3)` distance `=(3-0)+(3-2)=4`
`:.ltVgt.=(4)/(5)=0.8m//s`
`(4)` Slope is zero between `t=3` & `4 sec`
