Answer on Mechanics | Relativity Question for Som
After 22 seconds trolley carries mass of grain 16 kg - 11 kg = 5 kg
Total mass before the leakage m1 = 20 + 16 = 36 kg
Total mass after leakage m2 = 20 + 5 = 25 kg
From the momentum conservation law we have:
p1 = p2 or
m1*v0 = m2*v
Then the velocity after 22 seconds will be
v = v0*(m1/m2) = 20 m/s * (36 kg/25 kg) = 28.8 m/s

Thank u very much
Dear sundeep, thank you for your question. Look at the modified answer above.
what is the value 1.8..? mass/velocity...? can anyone explain the relationship used here..
