Question
A body is projected at such angle that the horizontal range is three times the greatest height. The angle of projection is
Options
A.42o8′
B.53o7′
C.33o7′
D.25o8′
Solution
R = 3H; R = 
2sin θ cos θ =
tan θ =
⇒ θ = 52o7′
2sin θ cos θ =
tan θ =
⇒ θ = 52o7′Create a free account to view solution
