Question 193: Motion in 2D & Vectors

Question

For angles of projection of a projectile at angle (45o $$-$$ $$	heta $$) and (45o + $$	heta $$), the horizontal range described by the projectile are in the ratio of

Accepted Answer

(45ÃÂº Ã¢ÂÂ $$	heta $$) & (45ÃÂº + $$	heta $$) are complementary
angles as 45ÃÂº Ã¢ÂÂ $$	heta $$ + 45ÃÂº + $$	heta $$ = 90ÃÂº. We know that if
angle of projection of two projectiles make
complementary angles, their ranges are equal.
In this case also, the range will be same. So the
ratio is 1 : 1.
