The range of a projectile at 30° is R30 and at 60° is R60 then
Correct answer: D. R30 = R60 if initial velocity are same
- A. R30 = R60
- B. 2R30 = R60
- C. R30 = 2R60
- D. R30 = R60 if initial velocity are same
Explanation
The range of projectile at 30° and 60° will be the same, if they are thrown at same speed.If two bodies thrown at same speed at angles such that their sum =π/2 then both of them will have the same range. (Because due to this value of sin(2θ) will not change. )

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
