In a collision between a stationary and a moving train, the damage to the moving train is huge.explain how and why using laws of motion or inertia

Open in App

Solution

When this moving train suddenly collides against a stationary train, there is a large change in the momentum of the moving train. This large change in momentum of the train is brought about in a very short interval of time.
Thus, according to newton's second law of motion (Force=Change in momentum/Time taken), a large retarding force acts on the train. Due to this large force, huge damage to the train takes place.

Q. A train moving with a velocity of

The driver of train A moving at a constant speed of $30 m / s$ sees another train B moving on the track at a speed of $10 m / s$ in the same direction. He immediately applies break and achieves a uniform retardation of 3m/s². To avoid collision, what must be the minimum distance between the trains?
