Question

Two bodies are thrown with the same initial speed at angles `alpha and (90^(@) -alpha)` with the horizontal. What will be the ratio of (a) maximum heights attained by them and (b) horizontal ranges ?

Answer 1

`(H_1)/(H_2) = (sin^(2) alpha )/( sin ^(2)(90^(@) -alpha))=tan ^(2) alpha `
`(R_1)/(R_2) = (sin2 alpha)/( sin2 (90^(@) -alpha)) =1 `
