The forces applie

From the second law of motion we know that

Then, acceleration can be calculated as

for first body

for second body

the ratio is, therefore,

OR

Given: Mass of train = m = 200 Kg

Velocity of the train= v = 36 kmph = 36 × 5/18 = 10 m/s

Now, the momentum of a body is given by

On substituting the value of m & v we get,
