Question

a body is projected in such a way that the horizontal range is three times the greatest height the angle of projection.

Answer 1

★Hi , Everyone !!!!★


R = u²sin 2∅ / g = 3 H = 3 u² sin² ∅ /2g

=> u² sin2∅ /g = 3u² sin²∅/2g

=> 2sin∅ cos∅ = 3sin² ∅/ 2


2sin∅ Cos∅ = 3 sin∅ /2

tan ∅ = 4 / 3



∅ => tan ^ -1 ( 4 / 3 )





hope it helps you!!!


thanks !!!
