Question

A train moves in a straight line with a uniform acceleration. If X and Y be the velocity with which the front and rear end of the train respectively cross of fixed pole then the velocity with which the middle of the train crossing the pole is?​

Answer 1

Answer:

The velocity with which the middle of the train crossing the pole is

$v = \frac{x + y}{2}$

Explanation:

As the acceleration is uniform, thus to find the velocity at the mid, just find the average which is the answer.
