1. The problem statement, all variables and given/known data A body falling from rest from given height H hits an inclined plane in its path at height. As a result of this impact the direction of velocity of the body becomes horizontal. For what value of h/H will body take max time to reach the ground? ANS) h/H = 1/2 2. Relevant equations Newtons equations of motion Projectile equations 3. The attempt at a solution v2 = u2 + 2as v2= 2 * 10 * (H-h) now time of flight of projectile from inclined plane T = 2*v*sinx/g*cosy (x being angle of projection and y angle of incline) this has to be equal to time of projectile dropped with no initial velocity T = (2h/g)1/2 equating and substituting i get the answer to be h/H = 4/5 (which is not the correct answer) Please help!
