Range of a projectile on a horizontal plane is same fo the following pair of angle:
Correct answer: C. 75 & 15
- A. 60 & 20
- B. 15 & 30
- C. 75 & 15
- D. 50 & 25
Explanation
For a given initial velocity, the range is the same for angles that add up to 90 degrees, such as 75° and 15°.

About Projectile Motion
Projectile motion combines uniform horizontal motion with vertically accelerated motion under gravity, assuming air resistance is neglected. Questions use the components of initial velocity to find time of flight, maximum height, horizontal range and position, while distinguishing projectile motion from general circular or one dimensional motion.
