A train starting from rest attains a velocity of

$72\ km\ h^{–1}$ in

$5\ minutes$ . Assuming that the acceleration is uniform, find

(i) the acceleration and

(ii) the distance travelled by the train for attaining this velocity.

From the Equation of motion -

$I$ , We know that,

$i = i + (i \times i)$

From the Equation of motion -

$III$ , We know that,

$i \times i \times i = i^{i} - i^{i}$

Acceleration $=$

$\frac{i}{i}$

$m\ s^{-2}$

(Note: Enter your answer in fraction)

Distance travelled $=$

$km$

(Note: Enter your answers with no decimal places)
