Question

a ball projected at an angle of 45° with horizontal.it passes thru a wall of height h at horizontal dist d1 from pnt of projection & Strikes grnd at horizontal dist (d1+d2) from pnt of projection then relation btwin h, d1, d2 is best gvn by

Answer 1

Use the formula tanA + tanB = tanC
where C is the angle of projection and B and C are the angles made by the point on the path of trajectory with the point of projection and the point of landing respectively
