Answer:
Explanation:
In projectile motion , range of projectile is given by the expressions
R = u²sin2θ / g
where u is velocity of projectile.
u = 27 m/s θ = 50
12 = 27² sin 2θ / 9.8
sin 2θ = .16
θ = 9.2 / 2
= 4.6
When we place 90- θ in place of θ , in the formula of range , we get the same value of projectile. hence at 85.4 ° , the range will be same.
