11I'm giving u the outline for this......From the fact that the difference of the roots when (y=h)
is 2h, get the angle with which it was thrown from the eqn of the trajectory.....done!
3) A particle is projected with velocity 2(gh)^1/2 so that it just clears two walls of equal ht. h at a dist. Of 2h from each other. Find time of passing of particle between two walls.

1Find a quadratic equation in t (time). this will give 2 roots. smaller root is for the shorter distance and larger root for the larger dist.
