A ball is projected at an angle of 45^ with the horizontal. It passes through a wall of height ' h ' at a horizontal distance d₁ from the point of projection and strikes the ground at a distance d₁+d₂ from the point of projection, then ' h ' is

Options

  1. Ah= 2 d₁ d₂ d₁+d₂
  2. Bh= d₁ d₂ d₁+d₂
  3. Ch= 2 d₁ d₂ d₁+d₂
  4. Dh= d₁ d₂ 2 (d₁+d₂ )

Correct answer

B. h= d₁ d₂ d₁+d₂

Step-by-step solution

R=d₁+d₂= u^2 90^ g u ^2 ~g = d ₁+ d ₂ Using, y=x - gx ^2 24^2 ^2 h = d ₁ 45^ - d ₁^2 2 ( ~d ₁+ d ₂ ) 1 2 = d ₁ ~d ₂ ~d ₁+ d ₂
