Question

A train starts from rest. It moves through 1 km in 100 s with uniform acceleration. What will be its speed at the end of 100 s. (20 ms)train ​

Answer 1

Answer:

20

Explanation:

Distance = average velocity * time

so

1000m=average velocity *100s

average velocity = 10m/s

The train starts from rest, and moves with uniform acceleration, so

average velocity = final−velocity2 .

final velocity=10*2=20.
