A 25,000 kilogram train is traveling down a track at 20 meters per second. A cow wanders onto the tracks 75 meters ahead of the train, causing the conductor to slam on the brakes. The rain skids to a stop. If the brakes can provide 62,500 Newtons of friction, will the conductor have enough stopping distance to avoid striking the cow?

Question

1/2(25,000)(20M/S)^2= 500,000/62500n= 80 j

Is this correct? Thank you
