A particle is projected from the ground at t=0 so that on its way it just clears two vertical walls of equal height on the ground. The particle was projected with initial velocity u and at angle θ with the horizontal. If the particle passes just grazing top of the wall at time t=t 1 and t=t 2 then calculate. a. the height of the wall. b. the time t 1 and t 2 in terms of height of the wall. Write the expression for calculating the range of this projecting and separation between the walls.
