✸Given:-

➧ Initial velocity of Train(u) = 0m/s

➧ Final velocity (v) = 40 km/h = 11.1 m/s

➧ Time (t) = 10 min = 60×10 =600s

✰To Find :-

➧ Acceleration (a) of train ???

✰ Solution :-

By using first equation of motion

★ v = u +at

➠ 11.1 = 0 + a × 600s

➠11.1 = a × 600

➠ a = 111/6000

➠ a = 0.0185m/s²

∴The acceleration of train is 0.0185 m/s².

✰ Additional information ✰

Some equation of motion are:-

v = u + at

s = ut +  \frac{1}{2} at {}^{2}

v {}^{2}  - u {}^{2}  = 2as
