Question

a train starting from a railway station and moving with uniform acceleration attains a speed of 40 km/h in 10 Minutes its acceleration is:
A) 18.5 m/s²
B) 1.85 cm/s²
C) 18.5 cm/s²
D) 1.85 m/s²

Answer 1

HI there !

Initial velocity = u = 0
Final velocity = v = 40 km/hr = 1111.11 cm/s
Time = t = 10 min = 600 sec

Acceleration = a

a = v - u / t
   = 1111.11 - 0 / 600
   = 1.85 cm/s²

Answer 2

Answer:

1/54 m/s2
