The maximum height attained by a projectile when thrown at an angle with the horizontal is found to be half the horizontal range. Then is equal to

Options

  1. A⁻¹ (2)
  2. B6
  3. C4
  4. D⁻¹ ( 1 2 )

Correct answer

A. ⁻¹ (2)

Step-by-step solution

Maximum height, H₀= u² ₂ 2 g Range, R= u² 2 g Given, H₀= R 2 array llrl & & u² ² 2 g & = u² 2 2 g & & & =2 & & & =2 & & & = ⁻¹(2) array
