Question

The velocity of a train increases at a constant rate alpha from 0 to v

Answer 1

Answer:

The speed of a train increases at a constant-askIITians.

The speed of a train increases at a constant rate α from zero to v and then remains constant for an interval and finally decreases to zero at a contant rate β.

If l is the toatal distance described,

prove that the toatal time taken is l/v+v/2[1/α+1/β].
