A particle is projected with velocityÂ Â at such an angle that it just clears twoÂ walls of equal height h which are at a distance 2h from each other. Show that time of passing between the two walls isÂ

Given,Â

Velocity with which the particle is projected = 2Â

Height of the wall = h

Distance between the walls = 2h

Let the particle be projected at angle Î¸.

Time taken by particle to cross the two walls each of height 'h' is equal to difference of instants when it would be at a height h above ground.

The kinematics of motion of particle in vertical direction is given by,Â

That is,Â Â is the time of passing between the two walls.Â
