Missiles I, II, III, and IV are launched at 35o, 45o, 55o and 65o, respectively from the origin. The shortest distance will be covered by
Correct answer: D. Missile IV
- A. Missile I
- B. Missile II
- C. Missile III
- D. Missile IV
Explanation
In projectile motion, the optimal angle for maximum range is 45°. Missiles launched at angles deviating from this will cover shorter distances. Missile IV, launched at 65°, is furthest from the optimal angle, resulting in the shortest range. Missile II, launched at 45°, achieves maximum range, while Missiles I and III, launched at 35° and 55°, respectively, cover distances shorter than Missile II but longer than Missile IV.

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.
