Question

if the velocity of a train starting from rest is 54km/hr after 5 mins what is its acceleration?

Answer 1

Answer:

0.05 m/s²

Explanation:

final velocity (v) = 54 km/hr = 15 m/s

time(t) = 5 min = 300 sec

initially at Rest (u) = 0m/s

Kinematics' equations: v = u +at

---> 15 = 0 +a(300)

---> 15 = 300a

--->a = 15/300 = 0.05 m/s²
