Question

A train starting from a railway station and moving with uniform acceleration

attains a speed 40 km h–1 in 10 minutes. Find its acceleration.​

Answer 1

Explanation:

Answer:

Given parameters

Initial velocity (u) = 0

Final velocity (v) = 40 km/h

v = 40 × (5/18)

v = 11.1111 m/s

Time (t) = 10 minute

t = 60 x 10

t = 600 s

Acceleration (a) =?

Consider the formula

v = u + at

11.11 = 0 + a × 600

11,11 = 600 a

a = 11.11/600

a = 0.0185 ms-2
