From a tower of height H, a particle is thrown vertically upwards with a speed u. The time taken by the particle to hit the ground is n times that taken by it to reach the highest points of its path. What is the relation between H, u, and n?

Time to reach the maximum height = t1 = u/g If t2 is the time taken to hit no ground, then -H=ut2-1/2gt2<sup>2</sup> It is given... View Article
