Question

a train starting from rest moves with acceleration of 5m/s². Find it's velocity when it has traveled a distance of 1 km​

Answer 1

Explanation:

Given:

u = 0

a = 5m/s^2

s(distance) = 1km = 1000m

v = ?

v^2 - u^2 = 2as

v^2 - 0^2 = 2 × 5 × 1000

v^2 = 10000

v = 100

v = 100m/s. and......
