HELLO DEAR,

GIVEN:-
MASS (m) = 9000kg
kinetic energy (k) = 18000j

we know :-
k = 1/2 mv²

therefore,
18000 = 1/2 × (9000) × v²

v² = $\bold{\frac{18000 \times 2}{9000}}$

v² = 36/9

v² = 4

v = 2m/s

hence, option (A) is correct,

I HOPE ITS HELP YOU DEAR,
THANKS

A freight train rolls along a track with considerable momentum. If it were to roll at the same speed but had twice as much mass,

fomenos

Answer:

The momentum would be doubled

Explanation:

The magnitude of the momentum of the freight train is given by:

$p=mv$

where

m is the mass of the train

v is its speed

In this problem, we have that the speed of the train is unchanged, while the mass of the train is doubled:

$m'=2m$

therefore, the new momentum is

$p'=m'v=(2m)v=2(mv)=2p$

so, the momentum has also doubled.
