How long does it take for a high-speed train to come to a complete stop?

In summary, a train comes to a complete stop when the brakes are applied, either manually or automatically. The time it takes for a train to stop depends on factors such as speed, weight, and track conditions. In emergencies, trains are equipped with emergency brakes that can stop the train in seconds. Failure to come to a complete stop can result in serious incidents, which is why proper maintenance and following safety procedures are crucial to ensure a safe stop.

A high speed train traveling at 84 kph locks its wheels and skids 84 meters before coming to a complete stop. If the rate of slowing down is constant, how many seconds will it take for the train to come to a complete stop?

Show your attempts.
State the relevant kinematic equations.

i tried converting kph to mps and then seeing how many seconds but the answer was wrong

Show your calculations.

84 kph = 23.333333 mps

84m/23.33333 mps = 3.6s

Write down the kinematic equations.
 

1. What causes a train to come to a complete stop?

A train comes to a complete stop when the brakes are applied. This can be done manually by the train operator or automatically by the train's signaling system.

2. How long does it take for a train to come to a complete stop?

The time it takes for a train to come to a complete stop depends on various factors, such as the speed of the train, the weight of the train, and the condition of the track. On average, it takes a train traveling at 60 mph to come to a complete stop in about one mile.

3. Can a train come to a complete stop in an emergency?

Yes, trains are equipped with emergency brakes that can bring the train to a complete stop in a matter of seconds. These brakes are typically only used in emergency situations, such as an obstacle on the tracks or a signal indicating danger.

4. What happens if a train fails to come to a complete stop?

If a train fails to come to a complete stop, it can result in a collision with another train, a derailment, or a collision with a stationary object. This can cause serious damage and injuries, which is why train operators are trained to prevent such incidents.

5. How can we ensure that a train comes to a complete stop?

To ensure that a train comes to a complete stop, proper maintenance of the train and its components is crucial. Additionally, train operators must strictly follow all safety procedures and signals to ensure a safe and timely stop. Regular training and monitoring of train operators can also help prevent any incidents.
