A50,000 kg locomotive is traveling at 10 m/s when its engine and brakes both fail. how far will the locomotive roll before it comes to a stop? assume the track is level.

2551.02 m

Explanation:

Given that, the mass of a locomotive is,

coefficient of friction for steel,

Velocity of the locomotive is

By conservation of energy it can be written as:

Here, E is the energy because of friction.

Now,

Here, m is the mass, v is the velocity of an object.

Now energy of the friction can be written as,

Here, is the coefficient of friction , m is the mass and g is the acceleration due to gravity.

Therefore

Substitute all the variables.

The distance traveled by the locomotive ball before stopping is 2551.02 m

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
