Answer 2

Given :-

The initial velocity of the train = 0 m/s⁻¹

Terminal velocity of the train = 40 km/h

Time interval = 10 min

To Find :-

The acceleration of the train.

Solution :-

We know that,

• u = Initial velocity
• t = Time
• v = Final velocity
• a = Acceleration

By the formula,

$\underline{\boxed{\sf Acceleration= \dfrac{(v-u)}{t} }}$

Given that,

Initial velocity (u) = 0 m/s⁻¹ (at rest)

Final velocity (v) = 40 km/h = 11.11 m/s⁻¹

Time (t) = 10 min = 600 sec

Substituting their values,

a = (11.11 - 0)/600

a = 0.0185 m/s⁻²

Therefore, the acceleration of the train is 0.0185 m/s⁻².
