What is the mass of the train?
The mass of the train is <u>1.5 kilograms.</u>
Answer:
Explanation:
Given that
Length = L
At initial over hanging length = Xo
Lets take the length =X after time t
The velocity of length will become V
Now by energy conservation
So
We know that
At t= 0 ,X=Xo
So we can say that
So the length of cable after time t
