Question

Its this sum: PLS HELP!! I'LL mark as brainliest if answer matches! Thanks

Answer 1

Given:-

total mass =1000 + 4×2500 = 11000 kg

total friction due to wagon = 2500 × 4 = 10000N

1) Fnet = Force by engine - Friction force

= 50,000 - 10,000

= 40,000 N

2) acceleration = Fnet / total mass

a =( Force by engine -Friction )/ Total mass

a = 50,000 - 10,000 / 11000

a = 3.36 m/s2

3) Force on wagon 2 by wagon1 = Mnet × acceleration

F = ( mass of 3 wagon )×a

= 3 × 2500 × 3.36

= 25200N
