A runaway train car that has a mass of 15,000 kg travels at a speed of 5.4 m/s down a track. Compute the time required for a force of 1500 N to bring the car to rest.
Step 1 of 4
Train car of mass travelling at a speed of on a track. Here we need to calculate the time required to bring the train car to rest by applying a force of .
Using newton's second law, we can calculate the time required to stop the train car.
