Question

a train starting from rest attains a velocity of 180 km per hour in 15 minutes. assuming that the acceleration is uniform find the distance traveled by the train for attaining this velocity.​

Answer 1

Answer:

the distance travelled by train for staying this velocity is 3 km

Step-by-step explanation:

Given:-. initial velocity (u)=0

final velocity. (v)= 72km/h

time (t)= 5min , here it is given in min so it will first convert into hour

5min = 5/60= 1/12hour

then , applying 1st eq of motion

ie. V=u + at------- v-u/t=a

72- 0. =864km/h----- acceleration

1/12

now , distance travelled by train

S=u t +1/2 at*2

=0×1/12+1/2×864×(1/12)*2

=1/2×864×1/144

=3km ... Answer

I hope this will help you....
