Question

A train starting from rest attains a velocity of 72 km h-'in 5 minutes. Assuming that the the acceleration is uniform, find the acceleration and distance travelled by the train for attaining this velocity.​

Answer 1

solution:

we have been given

u=0 ; 72km h-' =20m s-' and t =5 minutes = 300s .

(i) from Eq . (8.5) we know that

a = (v - u) / t

= 20m s-' -
