Question

for angles of projection of a projectile at angles (45 degree -thetta) and (45 degree + thetta), horizontal ranges described by projectile are in ratio​

Answer 1

Answer:

(1) 1 : 1

Explanation:

if angles of projection are complementary to each other keeping projection speed constant , then, their ranges are equal.

here ,

(45° + theta) + (45° - theta) = 90°

.....

hope , it helps you.

Answer 2

Hy dear...

The answer is 1:1

..

We know that for complemetary angles the range will be same (onlyif the Object has same initial velocity).

And ....

(45° + @ ) and (45° - @ ) are complemetary angles

Therefore...

the range will be same .

Hope it helps u.......
