Question

if the velocity of a train starting from rest become 20m/s in 10 second . what is it's acceleration?

​

Answer 1

Answer:

2 m/s²

Explanation:

Given:

Initial velocity (u) = 0 m/s   (as it started from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 seconds

To find:

a (acceleration)

Method to find:

v = u + at

⇒ 20 = 0 + 10a

⇒ a = 20/10

⇒ a = 2 m/s²

Hence, the acceleration of the train is 2 m/s².
