A projectile projected at an angle 30degree from the horizintal has a range R. if the angle of projection at the same intial velocity be 60degree ,then the range will be...

Answered by therase

$r = {u}^{2} sin2 \alpha \div g$

therase: sorry the answer is not complete . here sin60=sin120 therefore the range will be same. that is it will also become R

yabhi3704: how it is ?

therase: here Intial angle is 30 that is according to the equation sin function become sin 2×30 =sin 60 other all terms didnt change even in the second case.In the second case angle is 60. that is sin function become 60×2 =120.here sin 60= sin 120. therefore all the terma are equla. therefore on change in R

yabhi3704: thanks
