station and moving with uniform
acceleration attains a speed
40 km h-i in 10 minutes. Find its
acceleration.
103​

Answer 1

Explanation:

Known Terms:-

u = Initial speed

v = Final speed

a = Acceleration

t = Time

Given:-

Initial speed of the train, u = 0 km (Because train starts from the rest.

Final speed of the train, v = 40 km/h = × 40 = 11.11 m/s.

Time taken to attain the speed = 10 minutes = 10 × 60 = 600 sec.

To Calculate:-

Acceleration of the train.

Answer 2

Answer:

here, initial velocity, u = 0 m/s

final velocity ,v= 40 km/hr = 11.11 m/s

time, t= 10 min = 600 sec

acceleration = (v-u)/t

= 11.11/600 = 0.0185 m/s²
