A person walks on a traveling train. The person is walking at a speed of 0.5 m/s in the southward direction with respect to the earth. The train is traveling at a speed of 1.5 m/s in the northward direction with respect to the earth. What is the velocity of the person with respect to the train

2 m/s

Explanation:

It is given that,

The velocity of a person is 0.5 m/s in the southward direction with respect to the earth.

The velocity of the train is 1.5 m/s in the northward direction with respect to the earth.

We need to find the velocity of the person with respect to the train. Let it is v.

When two objects are moving in the opposite direction, the relative velocity is equal to the sum of velocities.

Velocity of the person with respect to the train = 0.5 m/s + 1.5 m/s

= 2 m/s

Hence, the velocity of the person with respect to the train is 2 m/s.
