Question

A particle starting from rest begins to move along a straight line with acceleration a. Its complete path x is divided into n equal parts. At the end of each part, its acceleration increases by a/n. Prove that the velocity of the particle at the end of the path is √[ax(3n – 1) /n]​

Answer 1

Answer:

use the formula v 2=u2+2as

then a= in arithmetic progression.

u=0

then v=rootover()
