Example 4.31
A stone s1 is projected from point p with speed v and angle of elevation theta1.
Another stone s₂ is projected with the same speed v from point p at an angle of
elevation theta2, where tan theta2=2tan theta 1. If R₁, h, and R2, h2; are respectively the ranges
and maximum heights and R₁:R2 = 15:25, find the ratio h1:h₂.
