Which pair of launch angles below will travel the same range given the same initial velocity?
A) 30° and 50°
B) 25° and 35°
c) 40° and 50°
D) 30° and 70°

To Find :

Which of the given pair of launch angles below will travel  the same range given the same initial velocity.

Solution :

We know, two projectile with same velocity and different angles a and b can have same initial velocity on when the following condition satisfies :

a + b = 90°

Now, putting all the given value in above condition, we get for value 40° and 50° the above condition is true.

Therefore, option c) is correct.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
