Question

An express train passes through a station. it enters with an initial velocity of

A) 0 m/s
B) Constant speed
C) Variable speed
D) Maximum speed

Answer 1

The correct answer is C) Variable speed.

Step-by-step explanation:

The correct answer is C) Variable speed.

An express train is a type of train that travels at a higher speed than regular trains, making fewer stops and reaching its destination faster. Unlike regular trains, which may have a consistent speed throughout the journey, an express train can have a variable speed.

For example, an express train may start with an initial velocity of 0 m/s at the station, gradually increase its speed to a maximum speed, and then decelerate as it approaches the next station. This variable speed allows the express train to cover long distances in a shorter amount of time compared to regular trains.
