A Projectile takes off with an initial velocity of 10 m/sec at an angle of elevation of 45 degrees. It is just able to clear two hurdles of height 2 m each , separated from each other by a distance d. Let x denote the distance between point of projection and first hurdle.

Calculate x+d .

Details And Assumptions

Firstly calculate x and d upto 2 decimal places and then enter there sum upto 2 decimal places for ensuring correct answer.

Take g = 10 m/sec^2
