Answer 2

Answer:

We will divide the problem into 3 parts.

Part1:- Vi=0 Vf=48kmph= 48×1000/3600=40/3mps T=2minutes=2×60=120s. S1=?

Formula:2as=Vf2 - Vi2

We have to find acceleration.

Formula of acceleration: Vf=Vi±at, 40/3=0±a×120, 40/3×120=a, a=4/36mps2.

2as=Vf2-Vi2, s× 2×4/36=(40/3)2-0, s=1600×36/2×4×9, s=1600×36/2×36, s= 1600/2 s=800 (S1=800m)..

Part2: In part2 motion of train is uniform therefore we find the distance by this fromula

S=V×T V=48kmph=40/3mps S2=? T=5m=5×60=300s.

S=40/3×300=4000 (S2=4000m)..

Part3: Vi=48kmph=40/3mps Vf=0 T=3m=3×60=180s S3=??

Formula: 2as= Vf2 - Vi2 We have to find acceleration here too.

Vf= Vi ± at, 0= 40/3 ± a×180, -40/3×180=a, a= -2/3×9, a=-2/27.

2as= Vf2 - Vi2 s×2×2/27= 0 (-40/3)2, s×4/27=1600/9, s= 1600×27/4×9, s= 1600×27/36, s= 1600×3/4, s= 4800/4=1200

S3=1200m.

Total distance= 800±4000±1200= 4000m
