Question

a train increases its velocity 18km/h to 108km/h in time 1minute find its acceleration​

Answer 1

Answer:

acceleration= Δv / Δt

=108 -18 /0.0166667

=90/0.0166667= 5400 km/h

5400km/h= 1500m/s

Explanation:

Answer 2

Answer:

18km/hr * 5/18 -> 5m/s

108km/hr * 5/18 -> 30m/s

1minute -> 60s

a = v - u / t

a = 30m/s - 5m/s / 60s

a = 25m/s / 60s

a = 5/12m/s^2

a = 0.41m/s^2

hope it helps
