Question

A train starting from the railway station in uniform acceleration attains the speed 40 km h-¹. Find it's acceleration?

Answer 1

acceleration =final velocity-initial velocity/time 40×5/18=final velocity

initial velocity =0ms hence the question can be solved in this manner

Answer 2

Answer:

Here we have,

Initial velocity, u = 0,

Final velocity, v = 40km/h = 11.11m/s

Time (t) = 10 minute = 60x10=600s

Acceleration (a) =?

We know that=

v=u+at

11.11=0+600a

a=11.11/600

a=0.0185 m/s
