Question

train is moving with uniform velocity of 30 M per second passenger in the train fires two identical guns one in direction of motion and other in opposite direction. Find the velocity of one bullet with respect to the other

Answer 1

Relative velocity of one bullet with respect to other will be -2v m/sec

Explanation:

We have given that train is moving with uniform velocity 30 m /sec

Let the velocity of the bullet is v m/sec

So relative velocity of the bullet when it is fire in the direction of moving train = 30-v m/sec

And So relative velocity of the bullet when it is fire in the direction of moving train = 30+v m/sec

Now relative velocity on bullet with respect to other = 30-v-(30+v) = 30-v-30-v = -2v m/sec
