Question

A train travels along a straight piece of track between 2 stations

A and B. The train starts from rest at A and accelerates at
1.25m/s² until it reaches a speed of 20m/s. Find the distance
from A to B.

Answer 1

v=20m/s ,u= 0m/s( from rest) a=1.25m/s Distance s=?

V²= UT +2as

make s subject

2as=v²-u²

S= v²-u²/2a

S =20²-0²/2*1.25

S=400/2.5

S= 160m
