Question

A train starting from just attains a velocity of 72 km h -1 in 5 minutes assuming that the acceleration is uniform find​

Answer 1

Answer:

v=u+at 

a=(v-u)/t                   -----------(1)

v=72 km/h

 =20m/s

u=0

t=5*60 sec =300sec

by putting values of v,u,t in (1)

a=1/15 m/s2

s=ut +(1/2)at2

 =0+(1/2)(1/15)(300)(300)

=3km

Explanation:

Hope it helps u
