A Train Starting from a Railway Station and Moving with Uniform Acceleration Attains a Speed of 40 km hr-1 in 10 Minutes.Find its Acceleration in the Units of ms-2?

Answer : With the parameters provided,

Initially, the velocity (u) is set to zero.

Final Velocity, v= 40km/hr = 11.11m/s.

Time, t = 10 minutes =600 seconds.

Acceleration, a = ??

Now, by using the formula

v = u + at.

Here,

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration.

Now, putting the value of v, u and t in the formula

11.11 = 0 + 600a

a = 0.0185 m/s² .
