Answer:
The right answer is "1.369 m/s²".
Explanation:
The given values are:
Distance (s)
= 260 m
Initial speed (u)
= 26 m/s
Reaction time (t')
= 0.51 s
During reaction time, the distance travelled by locomotive will be:
⇒
Remained distance between locomotive and car:
⇒
Now,
The final velocity to avoid collection is, V = 0 m/s
From third equation of motion:
⇒
On putting the estimated values, we get
⇒
⇒
⇒
⇒
⇒
Ignore the displacement formula
