We have equation of motion v = u + at
Where v = final velocity, u = initial velocity, a = acceleration, and t = time
In this case car is travelling in -x direction
Velocity of car = displacement / time
Since displacement value is increasing in negative x axis it's initial velocity is negative
And it's final velocity is zero since it comes to rest, and time is also positive
So, v= u+ at => 0 = -u + at
So, a = u/t
Which is positive and along positive X - direction
The <span>researchers </span>might not get accurate results because of the following points:
1) The students may lie about the drug use.
2) The students may write correct information and might later feel guilty of writing the truth.
3) High school Students dont know much about drug types and its usage.
